Brain

Brain Parts

• Hypothalamus
• Thalamus
• Cerebellum - major role in motor control. May also be involved in cognitive functions, such as attention and language as well as emotional control

• Cerebral Hemispheres/Cerebral Cortex - concerned with higher mental functions: perception, action, language, and planning. Contains about 100 billion neurons, each with about a thousand synapses, making a total of about 100 trillion synaptic connections
  • Frontal lobe - part of the neural circuit governing social judgements, planning and organization of activities, aspects of language, control of movement, and a form of short-term memory called working memory
  • Parietal lobe - receives sensory information about touch, pressure, and space around the body and helps integrate that information into coherent perceptions
    • somatosensory cortex - a strip in the parietal lobe contains Wilder Penfield's sensory homunculus.
  • Occipital lobe in involved in vision
  • Temporal lobe is involved with auditory processing and aspects of language and memory.
  • Basal ganglia - help regulate motor performance
  • Hippocampus - involved with aspects of memory storage
  • Amygdala - coordinates autonomic and endocrine responses in the context of emotional states
