Neurotransmitter Effects Too Much Too Little Drugs
Acetylcholine Learning, memory, muscles Trembling Alzheimers Caffeine
Serotonin Sleep, mood, pain, aggression Migraines Depression Cocaine
Dopamine Pleasure, reward, attention, arousal Schizophrenia Parkinsons Cocaine, caffeine,nicotine, MDMA
GABA General inhibition of neurons Drowsy Anxious Alcohol
Glutimate General excitation of neurons Tingly numbing Drowsy Caffeine

• Acetylcholine involved in voluntary movement,
  learning, memory, and sleep Too much
  acetylcholine is associated with depression, and
  too little in the hippocampus has been associated
  with dementia.Dopamine correlated with
  movement, attention, and learning Too much
  dopamine has been associated with schizophrenia,
  and too little is associated with some forms of
  depression as well as the muscular rigidity and
  tremors found in Parkinsons disease.Norepinephri
  ne associated with eating, alertness Too
  little norepinephrine has been associated with
  depression, while an excess has been associated
  with schizophrenia.Epinephrine involved in
  energy, and glucose metabolism Too little
  epinephrine has been associated with
  depression.Serotonin plays a role in mood,
  sleep, appetite, and impulsive and aggressive
  behavior Too little serotonin is associated
  with depression and some anxiety disorders,
  especially obsessive-compulsive disorder. Some
  antidepressant medications increase the
  availability of serotonin at the receptor
  sites.GABA (Gamma-Amino Butyric Acid) inhibits
  excitation and anxiety Too little GABA is
  associated with anxiety and anxiety disorders.
  Some antianxiety medication increases GABA at the
  receptor sites.Endorphins involved in pain
  relief and feelings of pleasure and contentedness

• ACTING IN THE ENVIRONMENT. MOTOR SYSTEMS AND
  DISORDERS.
• Mapping the Motor Cortex
• Wilder Penfield, a Canadian surgeon, took the
  next exploratory voyage of the brain's
  organization starting in the 1950s. While
  operating on epileptic patients, Penfield applied
  electric currents to the brain's surface in order
  to find problem areas. Since the patients were
  awake during the operations, they could tell
  Penfield what they were experiencing. Probing
  some areas would trigger whole memory sequences.
  For one patient, Penfield triggered a familiar
  song that sounded so clear, the patient thought
  it was being played in the operating room. During
  these operations, Penfield watched for any
  movement of the patients' bodies. From this
  information, he was able to map out the motor
  cortex, the part of the brain you mapped out in
  this feature's activity.
