Document Summary

Ct, cat scan shows dense stuffs like bones with low resolution. Pet it shows proteins like dopamine or chemicals working as a neuron transmitter. Mri shows soft stuff like brain or fluid with high resolution fmri (functional mri) shows blood flow and brain activity by illustrating which brain area is soaking up glucose, or energy. Forebrain cerebrum, telencephalon, diencephalon (2 thalamus, 2 hypothalamus) Homeostasis, regulating or controlling sequences of hormone. Midbrain mesencephalon (cell nuclei cell soma, receiving end) Sends electrical messages like nerve impulses (i. e. fight or flight, feeding, seeking partner) to forebrain (i. e. action potentials) When the messages arrive in forebrain, neurotransmitters are released into synapses in the forebrain. Hindbrain metencephalon (cerebellum), myelencephalon (pons, medulla) Autonomic functions stable life support function (i. e. respiration, digestion) Central fissure (central sulcus, first crack in the brain) Parietal primary somatosensory (touch) processing, s1. Premotor strip, strategy, judgement, self, intentions, social cognitions, actions outcome (selecting most favorable outcome by acting)
