A dynamic neural network model of self-organized criticality in neuronal avalanches

2013 6th International Conference on Biomedical Engineering and Informatics, 2013

Self-organized criticality is one of the key mechanisms to explain the emergence of complexity in natural systems, which has been demonstrated in many physical systems. Recently, physiological experiments reported the convincing evidence that the spontaneous activity in brain cortex exhibited neuronal avalanches, which provided that self-organized criticality also play a crucial role in brain. The scientific problem for theoretical works ...

2005 IEEE Engineering in Medicine and Biology 27th Annual Conference, 2006

We have detected synchronized spontaneous Ca2+ spikes in cultured cortical networks in the presence of Mg2+. The synchronized spontaneous Ca2+ spikes are synaptically driven, as it is blocked by tetrodotoxin (TTX), and by the glutamate receptor antagonist CNQX/APV. The oscillatory activity is not influenced by GABA A receptor antagonist picrotoxin, suggesting that they entirely rely on glutamatergic neurotransmission. We have ...

  • A dynamic neural network model of self-organized criticality in neuronal avalanches

    Self-organized criticality is one of the key mechanisms to explain the emergence of complexity in natural systems, which has been demonstrated in many physical systems. Recently, physiological experiments reported the convincing evidence that the spontaneous activity in brain cortex exhibited neuronal avalanches, which provided that self-organized criticality also play a crucial role in brain. The scientific problem for theoretical works is to analyze the dynamic mechanism of self-organized criticality in the neurosystem. A neural network model, based on the dynamic neurons and synaptic transmissions properties, was developed in this paper. Through the discussion of the balance between the excitatory and inhibitory neurons, the dynamic synaptic transmission process, synaptic plasticity and the temporal connecting structure due to the synaptic delay, we discussed the probable dynamic mechanisms in neuronal avalanches and the difference of the mechanisms of self-organized criticality between the neurosystem and other systems.

  • A novel microfabricated device measures a large fraction of hormone release from individual-cells with high time resolution

    Single-cell assays of hormone or neurotransmitter secretion have applications in cell-based biosensor development, high-throughput screening of drugs and basic science investigations. We are using microsystems technology to make electrochemical electrodes in picoliter-size wells for measuring catecholamine release from. individual cells. By making the well-electrode only slightly larger than the cell, high sensitivity and time resolution are achieved. The electrode can detect "spikes" of oxidative current corresponding to the release of individual catecholamine-containing vesicles from bovine adrenal chromaffin cells with millisecond time resolution. In, addition, we have simultaneously used whole-cell patch clamp recording to estimate that more than 60% of catecholamine released from the cell is captured by the well- electrode.

  • Software for characterizing the ionic basis of the molluscan cardiac action potential

    The goal of this modeling effort was to examine how individual membrane currents determine the repertoire of electrical signals recorded from bivalve cardiac action potentials. Software was developed in C++ (for both PC and Macintosh) and Java (Internet). A series of Hodgkin-Huxley equations described the kinetics of pacemaker activity, while a degree of customization was incorporated into the simulation, enabling the user to adjust parameters to accommodate a number of animal models. A graphical user interface was developed, suitable for demonstrating the dynamics of the system to students at the introductory level via the Internet. Modulation by molluscan neurotransmitters (5HT, FRMFamide, acetylcholine) was tested by adjustment of the respective ionic conductances. The model exhibited high sensitivity to minor alterations in model parameters and provided quantification of physiological recordings. The simulation software will be useful for developing hypotheses and interpreting experimental data, in an attempt to conduct more quantitative studies on invertebrate hearts. It is proposed that the model will be used as an educational tool for introducing ionic conductance and equilibrium potential as key components of the membrane potential in pacemaker mechanisms. This will be conducted in parallel with related animal investigations in the laboratory.

  • L-type calcium channels mediate synchronized spontaneous Ca<sup>2+</sup>spikes in cultured cortical networks

    We have detected synchronized spontaneous Ca2+ spikes in cultured cortical networks in the presence of Mg2+. The synchronized spontaneous Ca2+ spikes are synaptically driven, as it is blocked by tetrodotoxin (TTX), and by the glutamate receptor antagonist CNQX/APV. The oscillatory activity is not influenced by GABA A receptor antagonist picrotoxin, suggesting that they entirely rely on glutamatergic neurotransmission. We have also found that these Ca2+ spikes are dependent on an influx of extracellular Ca2+ but are independent of mobilization of Ca 2+ from intracellular Ca2+ stores. Ca2+ entry occurred primarily through L-type voltage-gated calcium channels (VGCCs), since nifedipine completely blocked these Ca2+ spikes

  • A throughput-on-demand address-event transmitter for neuromorphic chips

    The author presents a scalable 2D address-event transmitter interface designed to take advantage of the high integration densities available with advanced submicron technology. To sustain throughput, it exploits the linear increase in the number of active neurons per row with array size, instead of counting on a linear increase in the unit-current/unit-capacitance ratio, as existing designs do. The author synthesizes an asynchronous implementation starting from a high-level specification, and presents test results from a 104/spl times/96-neuron chip fabricated in a 1.2 /spl mu/m CMOS process. Reading out the state of all neurons in a selected row in parallel, and sending their spikes in a tight burst of events, yields cycle times between 40 to 70 ns-six to ten times shorter than the 420 ns minimum cycle time reported in earlier work.

  • Reproducing retinal rod bipolar cell light response by mathematical model including neurotransmitter receptors

    Detailed mathematical model of retinal cells is useful for the quantitative understanding of the subcellular processes of the visual system. Retinal bipolar cells receive information from photoreceptor cells, horizontal cells and amacrine cells, thus it can be considered as information integration system. Despite its importance, bipolar cell model including inputs and outputs has not been proposed. In this paper, we propose a rod bipolar cell model which can reproduce voltage response of light. The model includes TRPM1 channel which receives signal from photoreceptor cells, GABA channel which receives signal from surrounding amacrine cells, and cell body model which is based on the model proposed by Ishihara et al. The model was evaluated with several light signals, where experimentally obtained photoreceptor cell responses were used as TRPM1 channel input. Resulting bipolar cell membrane potential showed good agreement with the reported experimental results.

  • An efficient time-based CMOS potentiostat for neurotransmitters sensing

    A time-based potentiostat measuring electrochemical redox currents is described for the detection and quantification of neurotransmitters. The CMOS potentiostat is controlled by an adaptive sampling algorithm to increase power efficiency, input dynamic range and sampling frequency. The integrated circuit is characterized through post-layout simulation, using 0.13 μm CMOS technology. Results show a 94 dB dynamic range, a minimum sampling frequency of 1.25 kHz and a minimum analog power consumption of 13 μW per channel. The proposed electrochemical sensor is suitable for neurochemical in-vivo monitoring specifications.

  • Effects of Puerarin on Monoamino Neurotransmitter Levels in the Striatum of Cerebral Ischemia Rats

    This study was undertaken to examine the patterns of changes in extracellular fluid (ECF) dopamine (DA), orepinephrine (NE) and serotonin (5-HT) in the striatum of rats with middle cerebral artery occlusion (MCAO). The effect of Puerarin on monoamine neurotransmitter in the MCAO rats was also studied. Methods: Microdialysis was used to sample the brains extracellular space during 80 min of cerebral ischemia followed by 80 min of reperfusion. The microdialysate was measured by high performed liquid chromatography (HPLC). Results: It showed Puerarin could alleviate cerebral ischemia damage.

  • Multi-mode compliant digital enhanced transmitter architectures in nano-scale CMOS

    This paper treats two different transmitter concepts both enhanced by highly flexible and generic digital architectures. The first investigated transmitter is based on a state-of-the-art direct up-conversion transmitter extended with a digital front end and the second concept is a polar transmitter (PT). Crucial part is to mitigate radio frequency (RF) impairments by the means of digital compensation techniques, e.g. direct current (DC) and I/Q gain imbalance and digital predistortion. Both transmitter architectures are multi- mode compliant and shall support LTE, UMTS, CDMA2000, and GSM. Each transmitter concept utilizes a highly reconfigurable all digital phase locked loop (ADPLL). In the case of the direct up-conversion transmitter the ADPLL is used for RF synthesis and in the case of the PT it is used as phase modulator. Furthermore, measurement results for RF synthesis, realized by an ADPLL in a 130 nm complementary metal oxide semiconductor (CMOS) process technology, will be presented.

  • A study of a rectifying electrical synapse activated with a random action potential train

    A model of the rectifying electrical synapse of crayfish was developed based on the knowledge of the physiological mechanism. In previous work, however, its analysis was carried out only with a single action potential or steady DC current as a synaptic input. In this paper, we will attempt to understand the physiological properties of the electrical synapse with a random action potential train as its input at the pre-synapse. The results of numerical calculation in the time domain and the frequency domain suggest that the synapse has a low pass characteristic which influences the power density spectrum (PDS) of the output at the post-membrane side, It is also found that effects of the change in interpulse interval variance of the random input action potential train on the output PDS of the post-potential train are not as large as those of synaptic components.
