when learning a new skill‚ new synapses can be built in the appropriate part of the brain or body for you to remember and perform the skill better and faster. The ability and memory of the brain are practically boundless if the brain can refine its neurons‚ synapses‚ and pathways

Abstract The purpose of this experiment was to use the muscle tension and the electrical activity in the dominant and non-dominant forearm muscle‚ the flexor digitorum superficialis‚ to analyze the determinants of muscle tension and fatigue‚ and the reasons as to why differences may occur between the dominant and non-dominant arm. The generation of tension in a muscle is determined by the major type of motor unit being recruited‚ as well as the rate in which action potentials are being fired. A subject

Summer reading assignment 2013 Units 1 through 3 Unit 1: Psychology’s History and Approaches What is Psychology? Psychology is the science of behaviour and mental processes. Psychology’s common questions are: How do our minds work? How do our bodies relate to our minds? How much of what we know is already present/is acquired through experience? Psychology’s Roots: Asia/Middle East In India‚ Buddha focused on how sensations and perceptions combine to form ideas. In China‚ Confucious

reasons why the brain grows so vast at this period. During this time‚ there is a drastic increase in the connections between cells. This is to allows a more developed communication between each neuron to allow a more developed cognition. Meanwhile‚ the myelin‚ the fatty insulation that helps and protects the neuron‚ also grows and develops greatly. This will help speed up the electrical messages sent from

how the brain really works. Zimmer undergoes a mapping of his brain using Biomedical Imaging. According to the article‚ some neuroscientists are “zooming in on the fine structure of individual nerve cells‚ or neurons”‚ while others are using biochemistry to chart the brain to see how neurons produce different kinds of proteins. Others are trying to create detail to represent the brain’s wiring. Through all of these tests‚ scientists are getting a better understanding of the brain to understand disorders

Review Sheet Results 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Your answer: If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare

norepinephrine are released in the body‚ they tend to bind to receptors‚ tissues and neurons. These neurotransmitters transfer signals throughout the nervous system and stimulates action potentials in the postganglionic neurons. Receptors found on the ANS and PNS includes the cholinergic receptors‚ which consists of all sympathetic and parasympathetic preganglionic‚ sympathetic postganglionic and all parasympathetic postganglionic neurons. The cholinergic receptors are found in the postsynaptic plasma membrane

I SEMESTER STUDY MATERIAL B.A COGNITIVE PROCESSES AND BIO PSYCHOLOGY PSYCHOLOGY PREFACE Psychology can be defined as the scientific study of mental processes and behavior. While psychology is most often associated with clinical issues (i.e. abnormal‚ personality)‚ this makes up only a small portion of the field. Other specialties within the field include‚ to name a few‚ physiological‚ social‚ organizational‚ and developmental psychology. We cannot understand ourselves or the individuals
