Test Bank For Biological Psychology 13th Edition by James W. Kalat||ISBN NO:10,9781337408202| what is denervation supersensitivity? - answer like axon sprouting like compensates for lost connections. but instead of establishing new connections, it activates neurons with the same functions (the functionality is increased) what are neurotransmitters? - answer chemicals that lives in the brain the neurotransmitters in the synapse act as the key, and this needs to match with the correct...

Test Bank For Biological Psychology 13th Edition by James W. Kalat||ISBN NO:10,9781337408202| goals of psychology - answer observe and record facts in order to understand what is happening and to find and accurate description of human behaviour how did psychology gain recognition - answer Willhelm Wundt opened the first psychological lab to test theories and his lab were investigating: sensations, feelings, attention, perception, reacting time, and association difference between nat...

The Brain (CNS)Processes all incoming information from senses then controls the body

Consists of axons conveying messages from the sense organs to the central nervous system and from the central nervous system to the muscles Somatic nervous system What is composed mostly of myelinated axons that carries information from the gray matter to brain or other areas of spinal cord. White matter What are the two sections of the central nervous system? Brain & Spinal Cord What is contained in forebrain? Diencephalon, thalamus, hypothalamus, telencephalon, cerebral cortex, ...

What are action potentials? Travel along axons- The code the brain uses for behavior and thinking. Not based on the strength of the signal What is the all-or-none response? Actions potentials occur full on or none at all What is the neural signal based on? Frequency and which neurons are firing What are voltage-activated ion channels? Ion channels that open or close in response to changes in the voltage of the membrane potential What is the voltage threshold for initiation an...

Biological psychology application of the principles of biology to the study of physiological, genetic, and developmental mechanisms of behavior in human and nonhuman animals What does biological psychology do? it examines how experience, or environment, modifies brain and behavior Components of the stress response -metabolic mobilization -increased heart rate, blood pressure, respiration -redistribution of blood flow -suppression of immune, digestive systems -restores resting homeostas...

What are the divisions of the NS? Briefly describe each one. - CNS: brain and spinal cord - PNS: outside the brain and spinal cord - Somatic: interacts with *external* environment. Carries information from the body sense to CNS. Carries motor info from CNS to skeletal muscles - Autonomic: regulates *internal* environment. Carries sensory info from internal organs to CNS, carries motor info from CNS to internal organs - Sympathetic: prepares body to react and mobilise energy when...

Biological psychology a branch of psychology concerned with the links between biology and behavior Neuron a nerve cell; the basic building block of the nervous system Dendrite the bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body Axon the extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons or to muscles or glands Myelin a fatty substance that helps insulate neurons and s...

Biological psychology A branch of psychology concerned with the links between biology and behavior Neuron A nerve cell; the basic building block of the nervous system Sensory neurons Neurons that carry incoming information from the sensory receptors to the brain and spinal cord Motor neurons Neurons that carry outgoing info from the brains and spinal cord to muscles and glands Interneurons Neurons within the brain and spinal cord that communicate internally and intervene betw...

What is biological psychology? the study of how behavior relates to biological processes, especially to brain processes What 3 approaches relate brain and behavior? 1. manipulating the body may alter behavior 2. experience affects the body 3. bodily and behavioral measures covary Biological psychology seeks to understand the relationships between what 4 things? 1. somatic intervention 2. behavioral intervention 3. somatic variables 4. behavioral variables Biopsych contributes to o...
