An impulse has zero width in64257nite height and 64257nite area under it Math Mathematicians Impulses are distributions or generalized functions Dont call them Dirac delta functionsDirac would sue for de famation Def The impulse response of a syste — Struggle Between the Lower Self and the Superimposed Conscience. Lower Self. Inner Confusion and Battles. Now I would like to discuss one of the major causes of inner confusion and of the battles going on in the . How signals are sent through the nervous system. Synapse. Synapse. = Junction between . two. connecting neurons. Synaptic cleft-between the neurons,. signal has to go across this space. Signals need to be sent . What you need to know:. Three Basic Functions. Functional Organization. Neuron Structure. Reflex Arcs. Nerve Impulse physiology. Brain Structure/Function. Basic Functions. of the. Nervous System. Sensation. Sensory Receptors detect changes in our body and surroundings. Trigger nerve impulses. Travels to CNS for interpretation. Perceive a sensation. Types of Receptors. Chemoreceptors: changes in chemical concentration of substances. The . nervous. system is made of structures that . control . the actions and . reactions. of the body in response to . stimuli. from the environment. There are . two. parts: the . central. nervous system (CNS) and the . SUNY at Buffalo, School of Medicine. Department of Psychiatry. Objectives.
