"When a person glimpses the face of a famous actor, sniffs a favourite food or hears the voice of a friend, recognition is instant. Within a fraction of a second after the eyes, nose, ears, tongue or skin is stimulated, one knows the object is familiar and whether it is desirable or dangerous. How does such recognition, which psychologists call preattentive perception, happen so accurately and quickly, even when the stimuli are complex and the context in which they arise varies? Much is known about

Call 1600-111-533 (toll-free) for info. Formula Booklet – Physics XI Dear students Most students tend to take it easy after the board examinations of Class X. The summer vacations immediately after Class X are a great opportunity for the students to race ahead of other students in the competitive world of IITJEE, where less than 2% students get selected every year for the prestigious institutes. Some students get governed completely by the emphasis laid by the teachers of the school in which they

dynamics based simulations to study the effect of modified cut-off function for Tersoff potential on estimating mechanical properties of graphene G. Rajasekaran and Avinash Parashar* Department of Mechanical and Industrial Engineering Indian Institute of Technology, Roorkee - 247667, India * Corresponding author: E-Mail: drap1fme@iitr.ac.in, Ph: +91-1332-284801 ABSTART A modified cutoff function for Tersoff potential has been proposed in this paper, to estimate the realistic mechanical behavior of single

persons with MS but not pain. Persons with pain were also less likely to be employed. These findings are consistent with previous research that shows that pain is common in MS, that it is severe in a substantial subset of these individuals and has the potential to negatively impact physical and psychosocial functioning over and above the effects of MS

Structure Function Analysis of Sodium Channels in Human iPSC-derived Neurons Keywords: iPSC, sodium channel, electrophysiology, neuron, inactivation Background: Neuronal excitability mediated by sodium-dependent action potentials (APs) is required for rapid and specific communication in our brains. This underlies our ability to sense and respond to stimuli and for higher order cognitive functions including learning and memory. Voltage gated sodium channels (NaVs) open in response to membrane depolarization

influencing our lives. While he has achieved numerous achievements in various fields, this paper will focus on his achievements as a scientist and an inventor. As the scientist, he has established various scientific terms, especially terms that are used in electric physics. Ordinary people, even not professionals, use terms that Benjamin Franklin has established. In addition to that, as the inventor, he made various gadgets based on his knowledge. Even though we do not recognize it, his inventions and terms

Physiology of Membrane Potential 2.1 Understanding Membrane Potential 2.2 How to Calculate Membrane Potential 3. Transmembrane Potential 3.1 Measurement of Transmembrane Potential by Microelectrodes Summary In all cell types, there is an electrical potential difference exits between the inside and outside of the cell resulting from the differential concentrations of sodium and potassium

Nerve Exercise 1: Action Potential Threshold Using the Horizontal Compression buttons and the scroll bar display the data you wish to include in your report. Study Questions 1. How does a CAP differ from a single action potential? 1. How does a CAP differ from a single action potential? Answer CAP or compound action potential is a measure of the sum of the "all or none" single action potential of a group of fibers in a single nerve. The single action potentials are events that occur when

predict that the higher I drop the ball from the higher it will rebound up, because it will have more gravitational potential energy the higher dropped from. As it is dropped the ball will have kinetic energy, and then when it hits the ground changes to heat and sound energy, and kinetic as it rebounds back up. The higher up the ball is dropped from the more gravitational potential, more kinetic energy on the way down and therefore more sound heat and kinetic energy when hitting the ground. The ball

Alzheimer’s Disease accounts for sixty to seventy percent of dementia cases. The disease starts slowly and gets worse over time. The most common symptoms are short term memory loss, trouble with language , moods swings , and loss of movement. Communication networks are controlled by neurons . Neurons are the chief cells that get destroyed by Alzheimer’s disease. In the brain, neurons connect and communicate at synapses where tiny bursts of chemicals called neurotransmitters carry
