Neurobiology 3.1
Tags
Subcortical areas of the forebrain: Limbic system: emotional regulation
Amygdala: emotion, memory
Thalamus: relay center
Hippocampus: emotional regulation, memory
Hypothalamus: regulates homeostasis, interfaces with endocrine system
Imagining of the brain:
Radiation:
Computerized tomography:
-x-rays
-sees the structure of the brain (and any abnormalities)
Positron emission tomography:
-injects a radioactive substance(tracer) into one’s bloodstream
-follow the tracer as it flows through the body (when asked to think, the blood
rushes to our front brain)
-resolution isn’t great (show little detail)//exposure to radiation
-good for understanding neurotransmitter receptors.
Magnetic fields:
magnetic resonance imaging (MRI)
-creatures a strong magnetic field aligns all hydrogen atoms
-release energy when they snap back
-machine measures these burst of energy\
-machine measures these burst of energy
-structure of the brain
