Tremor is one of the most disabling symptoms in patients with many movement disorders including Parkinson's disease (PD) and essential tremor (ET). Neural tremor, which is measured by microelectrodes placed near nerve cells or obtained from brain cells during stereotactic neurosurgery, is due to the fluctuation of the firing rate of neurons. The frequency of this neural tremor varies over ...
Proceedings. 15th IEEE International Conference on Tools with Artificial Intelligence, 2003
This paper presents a brain based biometrics methodology using local global (L-G) and stochastic Petri net (SPN) graphs. In particular, today's most used lying detection systems (polygraph) are based on blood pressure under certain psychological conditions and have been proven inadequate and inaccurate for determining if a person is saying the truth or not. The main reason behind this inaccuracy ...

To study genotoxicity and oxidative damage induced by di-ethylhexyl phthalate (DEHP) in mice, different doses of DEHP were injected in the abdomen of the mice for 2 weeks. The effect of DEHP on DNA damage in nerve system of mice by celiac injection was examined by using single cell gel electrophoresis (SCGE) and the changes of the activity of superoxide dismutase (SOD) in liver, testicle and brain were also measured. Results showed that DEHP can induce DNA damage of nervy system of mice and DNA damage arouse along with the elevation of concentrations of DEHP (125, 375, 500 mg/kg.d). When the concentrations were 125 mg/kg.d and 375 mg/kg.d, DEHP can induce DNA strand breaks (p < 0.01, compared with control group) . The activity of SOD in liver, testicle and brain first arouse and then decreased alone with the rising of the doses. There were significant different in SOD activity in 375 mg/kg.d DEHP exposure group compared with that of the control. In conclusion, DEHP can induce DNA damage in nerve system of mice and oxidative damage in internal organs of mice with apparent dose-dependent manner.
Tremor is one of the most disabling symptoms in patients with many movement disorders including Parkinson's disease (PD) and essential tremor (ET). Neural tremor, which is measured by microelectrodes placed near nerve cells or obtained from brain cells during stereotactic neurosurgery, is due to the fluctuation of the firing rate of neurons. The frequency of this neural tremor varies over time and is nonstationary. We describe a frequency tracking method using the extended Kalman filter (EKF) to estimate the instantaneous tremor frequency (ITF) of binary spike trains detected from microelectrode recordings (MER). The results demonstrate that the EKF can accurately track fluctuations in tremor frequency even though the noise in binary spike trains is not Gaussian
This paper presents a brain based biometrics methodology using local global (L-G) and stochastic Petri net (SPN) graphs. In particular, today's most used lying detection systems (polygraph) are based on blood pressure under certain psychological conditions and have been proven inadequate and inaccurate for determining if a person is saying the truth or not. The main reason behind this inaccuracy is the psychological conditions under the test is contacting. Innocent persons with psychological fear to police or FBI agents may inappropriately react during the test producing false alarms, while at the same time guilty persons with acting capabilities may be lying and pass the test. Here in this paper we present a methodology based on fMRI and the way that the brain cells or brain regions interact regarding thinking and/or executing certain tasks. More specifically, fMRI provides color images for the active regions of the brain during thinking and/or performing certain tasks. These region-images are extracted and geometrically (topologically) are associated with the L-G graphs. Then using SPN graphs we represent their functionality. Thus, comparing the L-G and SPN graphs extracted from the candidate fMRI images to a set of "correct" generic L-G and SPN graph models available in an L-G/SPN graph database offers a more accurate measurement of the truth of false answers during the test. The main reason about the accuracy is that a liar will be detected because he/she will try to "think" how to avoid the truth.
Advances of note during 1991 are reviewed. A microprocessor-based fiber-optic sensing system that monitors blood gas in real time was introduced. Also introduced was a tympanic or ear thermometer that measures infrared heat generated by the eardrum and surrounding tissue and displays the temperature in about 2 s. Interest in artificial heart research was reviewed. Images of the human brain as it performed the simple task of recalling a word showed that the recall process was going on in unexpected parts of the brain, not just in the hippocampus.<<ETX>>
What is death? Over the centuries, the line dividing life and death has moved from the cessation first of breathing, then of the heartbeat, and finally of brain activity. But cryogenic methods first contemplated in science fiction may push the line even further. The idea is to freeze legally dead people in liquid nitrogen in the hope of regenerating them at some future date.
Summary form only given. This project proposes the use of Digital Signal Processing (DSP) for real-time capture and analysis of pathological slide images to improve accuracy and efficiency. Analyzing cell density statistics and average cell nuclei diameters of a slide image is useful to determine the abnormality of slide sample. Being tedious as it is in counting/measuring hundreds to thousands of cells in one sample slide under a microscope, the manual result, typically can be achieved by a pathologist, is often limited by human eye precision/efficiency. Millions of biopsy samples obtained daily around the world, from minor skin lesions to major tumors, are anxiously waiting to be screened/examined. As a high-level, interactive environment for data visualization/analysis/computation, MATLAB/spl reg/ is utilized currently to perform automatic image analysis and segmentation of brain cells on a computer. By comparing cell concentration and cell nuclei sizes between cancerous and normal image groups, MATLAB/spl reg/ can be programmed to distinguish normal brain cells from questionable ones. In general, pathological image analysis using a computer-based application could demonstrate great precision and efficiency for screening large quantities of cells on one or numerous sample slides. Currently, MATLAB/spl reg/ image analysis works on captured/digitized slide images and takes a minute per image to automatically pre-screen abnormalities that require further human expert analysis. With future real-time/parallel/machine-intelligent improvements, we hope that DSP can help physicians/pathologists/patients everywhere to get immediate diagnosis for effective/timely treatment, and can show accuracy within acceptable levels that are comparable to human pathologists in dealing with cell-overlapping and non-cell objects existing in slide images.
Traumatic brain injury (TBI) is responsible for approximately 80,000 permanently disabled persons per year, however, there is currently no pharmacological treatment for the head injured patient. The primary mechanical stimulus responsible for TBI occurs in less than a second, but is capable of initiating an extended cellular and molecular sequelae requiring hours or days or years to develop which results in the death of brain cells. A more thorough understanding of these molecular changes, including alterations in gene expression, could suggest new therapies for the TBI patient to either ameliorate detrimental or augment beneficial aspects of the post-traumatic sequelae. A novel in vitro model of TBI was developed to produce a precise and reproducible mechanical injury of long term organotypic brain slice cultures (OBSC) at strains and strain rates thought to be responsible for in vivo TBI. At 24 h after in vitro stretch injury, the expression of BDNF, NGF, and TrkA was increased whereas that of bcl-2, CREB, and GAD/sub 65/ was decreased. These results imply that apoptosis may play a role in cell death after TBI and suggest new therapies for the patient including infusion of growth factors such as BDNF or NGF.

This paper reports our 3D reconstruction work of mouse brain cells from a confocal image stack. Gradients at volumetric points are used for boundary surface extraction and structure visualization from 3D volumetric confocal microscopic images. We present a method to automatically evaluate the suitability of gradients for 3D boundary identification. The approach developed is applied for 3D reconstruction of mouse brain cells from confocal image stack
