Chapter 3.2 Flashcards
(11 cards)
Nerves 95
Nerves — bundles of neuron fibers (axons) that are touted together in the peripheral nervous system.
Peripheral nervous system 95
Peripheral nervous system— all the nerves that lie outside the brain and the spinal cord.
Afferent Nerve Fibers 96
Afferent Nerve Fibers — nerve fibers that carry information inward toward e central nervous system away from the peripheral nervous system.
Autonomic Nervous System (ANS) 96
Autonomic Nervous System (ANS) — made up of nerves that connect to the heart, blood vessels, smooth muscles and glands.
Efferent nerve fibers 96
Efferent nerve fibers — nerve fibers that carry information away from the central nervous system.
Somatic Nervous System 96
Somatic Nervous System — made up of nerves that connect to voluntary muscles and to sensory receptors.
Cerebrospinal fluid (CSF) 97
Cerebrospinal (CSF) — Nourishes the brain and provides a protective cushion.
Parasympathetic division 97
Parasympathetic Division — branch of the autonomic nervous system that generally so serves resources.
Sympathetic Division 97
Sympathetic Division — branch of the Autonomic nervous system that mobilizes the bodies resources for emergencies.

Focus: The linkage of Neurons to form networks
Book: The Organization of Behavior 1649
Contains:
Neurons do not act alone in influencing behavior but that they are linked in Cell Assemblies 91
Hebbian Learning Rule: Specifies how
these linkages might operate and come about.
“When an axon of cell A is near enough to excite a cell B and repeatedly or persistently takes part in firing it, some growth process or metabolic change takes place.”
Ideas referred to as the:
Hebb Synapse 92
Wilder Penfield 99, 101
Wilder Pennfield 99 -- 1954 Focus: Neuroscience and the mapping of functions of the brain
Accomplishments:
Founded the world-famous Montreal Neurological Institute and Hospital.
Specialized in the treatment of epilepsy
Penfield was able to stimulate portions of the brain with a mild electrical probe… systematically mapping out many of the fictions of the brain.
