Ventral Tegmental Area
- in the midbrain
- controls motivation and reward processing
How do drugs impact the ventral tegmental area?
- euphoria, increased motivation, drug seeking behavior, impaired decision making, restlessness, hyperactivity
Cerebellum
- in the hindbrain
- balance
- motor coordination
Pons
- in the hindbrain
- sleep/wake cycles
- dreaming
- panic/ anger
Medulla
- in the hindbrain
- breathing
- heart rate & blood pressure
- coughing/
/swallowing/sneezing - vomiting
What is in the hindbrain?
Pons, Medulla, and Cerebellum
What is in the midbrain?
Periaqueductal gray (PAG), Substantia nigra, ventral tegmental area (VTA), superior colliculus, interior colliculus
What is in the forebrain?
dorsal and ventral striatum, hypothalamus, thalamus, dorsal and ventral hippocampus, amygdala, olfactory bulb,
How do drugs impact the cerebellum?
balance problems, difficulties in coordination, speech problems, visual problems, vertigo
Cortex
- forebrain
- higher processes in the human brain
- memory
- thinking
- learning
- problem solving
- emotions
- consciousness
- functions related to senses
How do drugs impact the cortex?
memory issues, challenges with attention, emotional inadequacy, improper social behavior, inability to understand speech, speech problems, loss of muscle control over one side of the body
How do drugs impact the medulla?
- damage to medulla is usually fatal
- disruption to cardiovascular function, leads to paralysis or loss of sensation
Amygdala
- forebrain
- emotions (fear)
- emotional learning
- alcoholism
- anxiety
- PTSD
- aggression
How do drugs impact the amygdala?
irritability, confusion, strong emotions
How do drugs impact the pons?
can alter sleep patterns, may cause paralysis in face, changes in heart rate and blood pressure
Dorsal Hippocampus
- forebrain
- spatial learning
Ventral Hippocampus
- forebrain
- emotional learning and memory
How do drugs impact the hippocampus
memory impairment, cognitive impairment, confusion, disorientation, emotional regulation, hallucination, seizures
Hypothalamus
- forebrain
- thermoregulation
- hormone-driven behaviors
reproduction, aggression, stress, response, social - hunger and satiety
How do drugs impact the hypothalamus
appetite/eating behavior, body temp regulation, disruption in sleep patterns, increased sexual desire, anxiety
Corpus callosum
- movement control
- cognitive functions
- vision
How do drugs impact the corpus callosum?
impaired cognitive function, clumsiness, altered sensory perception, difficulties in communication, emotional changes
Prefrontal Cortex
- decision making
- impulse control
- perceiving consequences
- judgement
How do drugs impact the prefrontal cortex?
impaired executive function, impulsivity, impaired working memory, difficulty interpreting social cues, disrupted decision making, hallucinations
