CHAPTER 3
Roles
-
-
Axon
Carries information to the next cell; a long thin fiber that transmits signals away from the soma to the other neurons/muscles/glands.
Amygdala
Two Lima-Bean sized neural clusters linked to aggression and fear; plays a central role in the learning of rear response and the processing of the basic emotional responses
-
Endocrine System
Consist of glands that secrete c chemicals into the bloodstream that help control bodily functions
Temporal Lobe
Below the parietal lobe contains an area devoted to auditory processing " primary auditory cortex"
-
-
-
Motor Nervous System
Part of the central nervous system that is involved with movement, consists of the pyramidal and extrapyramidal system; falls under the Peripheral Somatic subdivisions.
Prefrontal cortex
A part of the brain located at the front of the frontal lobe. It is implicated in a variety of complex behaviors, including planning, and greatly contributes to personality development
Reticular Formation
Group of fibers that carry stimulation related to sleep and arousal through the brainstem
-
Medulla
Responsible for regulating the largely unconscious functions such as breathing and circulating; located in the hindbrain

2 Major parts of the nervous system
- Central Nervous System
- Peripheral Nervous System

-
Split brain visual verbal relation
Left half of visual field (left eye) delivers (picture) information to right visual processing area
Right half visual field (right eye) delivers (word) information to left visual processing area
All or None Law
- neural impulses either fire or they don't
- for its action potential the also either fire or don't but also they are all the same size
- nuerons can convert the strength of the stimulus; they do so by carrying the rate at which they fire action potential
- Stronger stimulus- rapid fire (weaker=Opposite )
How are hormones transported
Few circulate dissolved in the blood-stream, most are carried in the blood, bound to plasma proteins
-
-
What is / What are
Synaptic Cleft
A microscopic gap between the terminal button of one neuron and the cell membrane of another neuron; separates two nuerons
-
-
Brain Plasticity (examples)
- Studies have shown that aspects of experience can sculpt features of brain structure
- Research has shown that damage to incoming sensory pathways or the destruction of brain tissue and can lead to neural reorganization
- Adult Brain can generate new nuerons
-
Parts of the brain
-
-
Temporal Lobe
Below the parietal love on the top of temporary lobe contains an area devoted to auditory processing "primary auditory cortex"
Occipital Lobe
At the back of the head includes the cortical area where most visual signals are sent and visual processing is begun "primary visual cortex"
Parietal Lobe
Forward of the occipital love includes the area that registers the sense of touch "primary somatosensory cortex" also involved in integrating visual input and monitoring the body's position in space
Frontal Lobe
Largest lobe in the brain contains the principle areas that control the movement of muscles "primary motor cortex"
