Document Summary

Summarize hypothesis, rational, actual findings, limitations noted by the authors or by yourself. Neurons: basic building blocks, communication flow, basic parts (dendrites, soma, axon) Inside of cell body negatively charged (resting potential: excitatory post-synaptic potential (negative) Nervous system: afferent nerves to cns, efferent nerves from cns, mass communication, endocrine system (hormones, paul maclean -> evolution of nervous system (question of adding things on, animals have the same) Brain location, structure, function: midbrain structures, reticular formation - gatekeeper for info, prevents from waking up, tectum - sensory input, coordinating it, tegmentum - sensory input, movement. Forebrain structures: thalamus - info from senses integrated, basal ganglia - surround thalamus, associated with involuntary movement, hypothalamus - under thalamus, (4 f"s) fighting, fleeing, feeding, fornicating. Influences genes through mutation, genes influenced enviro: attracted to enviros. where we can thrive, temperament influence people around, personality & intelligence, development of personality, heritability coefficients, shared/unshared enviro. Intelligence heritability: twins concordance of . 75 (reared apart)
