The Brainstem (hind/old brain)

• Brainstem– located at the base of the brain, consisting of various parts functioning to sustain bodily functions.

2.6 What are the different structures of the bottom part of the brain?

The Old Brain (Brainstem)

• Medulla– Heartbeat and Breathing

• Pons “bridge”– Coordinates Movement and Sleep

• Reticular Formation– Net of Nerves Inside the Brainstem– Controls Arousal & Alertness– Example: When you name is called

• Locus Coeruleus– Center of Reticular Formation– Alertness and Panic

The Cerebellum “little brain”

• MAIN FUNCTION:– Coordinates

balance & movement

• (ex. Walking, playing guitar hero)

• OTHER FUNCTIONS:– Judges time– Stores muscle

memory– Discriminates

sounds and texture3

Structures Under the Cortex

• Limbic system – located under the cortex and involved in learning, emotion, memory and motivation

2.7 What controls emotion, learning memory and motivation?

The Limbic System (Emotional)

• Amygdala– Aggression and Fear

• Thalamus– Signal Switchboard– Relays information to your pleasure areas– Relays senses (not smell) information to cortex areas

• Ex: Information from eyes to visual cortex

• Hypothalamus– Hunger, Thirst, Sex, & Body Temp.– reward center & dopamine pathways

• Hippocampus– Memory

The Cerebral Cortex

• Frontal Lobes– Thoughts & Decision Making– Contains Motor Cortex– Contains Prefrontal Cortex

• In charge of logic, step-by-step decision making, morals, and emotional control

• Parietal Lobes– Sensation/Touch– Contains Sensory Cortex

• Occipital Lobes– Vision Processing– Contains Visual Cortex

• Temporal Lobes– Hearing & Memory– Contains auditory cortex
