• Introduction
• Role of neurotransmitters in brain functioning

4. Introduction
Brain is:
• most complex part of the human body
• the seat of intelligence,
• interpreter of the senses,
• initiator of body movement,
• controller of behavior.

5. • depend for controlling and coordinating actions and reactions, thinking and
feeling, and remembering and feeling
• all the things that make us human
• constantly being communicated by billions of neurotransmitter molecules that
regulate everything from breathing to heart rate to learning and concentration
levels.

8. Neurotransmitters Implicated in Antisocial &
Criminal Behavior & their role in Brain
Functioning
Neuro-transmitter Neuro-receptor Role in Brain Functioning
Acetycholine Cholinergic Involved in autonomic ganglia, many astronomically innervated organs, at
the neuromuscular junction, and at many synapses in the central nervous
system. Involved in learning and memory.
Dopamine Dopaminergic Involved in nerve impulses in the substantia nigra and vental tegmental
area. Involved in the control of locomotion, learning, working memory,
cognition, and emotion.
Abnormal functioning associated with various neurological and
psychiatric disturbances such as Parkinson’s disease, schizophrenia, and
amphetamine and cocaine addiction.
Gamma-aminobutyric
acid
.
(GABA)
GABAergic
Major inhibitory neurotransmitter in the central nervous system.
Implicated in anti-anxiety and relaxation

9. Neuro-transmitter Neuro-receptor Role in Brain Functioning
Glutamate Glutaminergic Involved in neural communication, and in brain development, learning,
memory, and cognitive function.
Norepinephrine/
noradrenaline
Adrenergic Involved in sympathetic nervous system, increases in arousal and alertness,
vigilance, formation and retrieval of memory, and focused attention.
Serotonin Serotonergic Involved in the regulation of mood, sleep, and appetite. Also involved in
cognitive functions, memory, and learning.
