Cerebral cortex
It plays crucial role in awareness, communication, memory, sensation, understanding, and the initiation of voluntary movements, as well as thought, reasoning, language, and consciousness - divided into 4 lobes
Temporal lobe
Olfaction, audition, language and emotion
Occipital lobe
Visual information
Frontal lobe
Motor control, decision making, and long term memory storage (executive-level function)
Parietal lobe
Touch, pain, and temperature processed in the somatosensory cortex
Thalamus
The primary sensory relay for everything except smell
Limbic system
Emotion, drive, and memory
Hippocampus
Part of the limbic system - and is essential for memory formation and recall
Amygdala
Part of the limbic system - and is involved in relating emotional meaning to memory
Hypothalamus
Part of the limbic system - and is used to regulate the autonomic nervous system
Substantia nigra
Plays a crucial role in movement, reward, and cognition - produces dopamine
Ventral tegmental area (VTA)
Is used for reward, motivation, and emotional regulation - produces dopamine
Medulla
COntrols the autonomic functions like breathing and heart rate
Pons
Connects the rest of the brain and regulates sleep
Cerebellum
Manages balance, coordination, and procedural memory
Bilateral
When there are 2 components - brain hemispheres
Corpus callosum
Where the sides of the brain connect
Functional magnetic resonance imaging (fMRI)
Measures brain activity through blood flow
Computerized tomography (CT) scans
Uses x-rays to visualize injuries, aneurysms, strokes, or tumors
Magnetic resonance imaging (MRI)
Similar to CT scans but uses magnetic fields and radio waves to visualize softer tissues
Positron emission tomography (PET)
Scans using mildly radioactive chemicals to monitor flow and metabolic activity
Electroencephalogram (EEG)
Measures brain waves as fluctuations in voltages
Regulatory genes
Change the expression of other genes in response to the environment
Epigenetics
Change the expression of other genes in response to the environment - molecular changes
