-Spinal Cord: passes messages from the brain, reflex actions, connects
to PNS
Peripheral Nervous System - ANSWER: Transmits Messages via
neurons
-Autonomic: breathing heart rate stress
-Somatic: muscle and sensory neurons
Endocrine System - ANSWER: the body's "slow" chemical
communication system; a set of glands that secrete hormones into the
bloodstream
Examples
-Thyroid, Thyroxine, heart rate

Localisation vs holistic theory - ANSWER: before Broca and Wernicke, ^&^
scientists supported the holistic theory of the brain that all parts were %$
involved in the processing of though and action. however, later scientists %^%
^%$
argued that different parts of the brain perform different tasks and %^%
are involved with different parts of the body. if the brain area is
damaged, the associated function will also become affected
Hemispheres of the brain - ANSWER: Right side is more Creative
(deals with art, music, holistic thought, and intuition). Left side is more
Analytical (deals with logic, language, science, and math).
Brain Localisation - ANSWER:
Brain Part Functions - ANSWER: Motor- movement
Visual- sight
Somatosensory- sensory
Auditory- analysis of sound based info
Broca's- Speech production
Wernicke's- language understanding

>not just broca and wernicke, fmri showed greater spread
Left and Right Hemispheres - ANSWER: Together, the two
hemispheres control much of your behaviour. The left is relatively more
specialized for speech and language; the right, for appreciation of 3D
space and spatial relationships. Right hem controls RVF and vice versa
Split brain research - Sperry - ANSWER: Sperry studied individuals
who had undergone a commissurotomy (corpus callosum cut to separate
the two hemispheres)
Images in both visual fields
When image shown to RVF (LH) they could descibe it but not on the
opposite side, as the RH could not relay to language centres in the LH
