Neurotransmitters2

  1. 1. Neurotransmitters An introduction
  2. 2. Definition of Neurotransmitters <ul><li>Chemicals located and released in the brain which allows communication from nerve cell to nerve cell. </li></ul>
  3. 3. Synapses <ul><li>There is a space between the two neurons called a synapse. It is in this space that the neurotransmitters gather, ultimately to the receptors on the other neuron. </li></ul>
  4. 4. Some famous neurotransmitters <ul><li>Acetylcholine: </li></ul><ul><li>Excitatory neurotransmitter </li></ul><ul><li>Triggers muscle contraction & release of some hormones </li></ul><ul><li>Involved in wakefulness, attentiveness, anger, aggression, sexuality </li></ul><ul><li>Dopamine </li></ul><ul><li>Inhibitory transmitter </li></ul><ul><li>Involved in controlling movement & posture </li></ul><ul><li>Modulates mood </li></ul><ul><li>Involved in positive reinforcement & dependency </li></ul>
  5. 5. More famous transmitters <ul><li>GABA </li></ul><ul><li>Inhibitory neurotransmitters </li></ul><ul><li>Contributes to motor control, vision and cortical function </li></ul><ul><li>Regulates anxiety </li></ul><ul><li>Glutamate </li></ul><ul><li>Excitatory neurotransmitter </li></ul><ul><li>Associated with learning and memory </li></ul>
  6. 6. And more neurotransmitters <ul><li>Norepinephrine </li></ul><ul><li>Important for attentiveness, emotions, sleeping, dreaming & learning </li></ul><ul><li>Also causes blood vessels to contract and HR to increase </li></ul><ul><li>Plays role in mood disorders </li></ul><ul><li>Serotonin </li></ul><ul><li>Contributes to functions such as body temperature regulation, sleep, mood, appetite and pain. </li></ul>
  7. 7. Scientists have identified over 60 different molecules that meet criteria to be considered neurotransmitters.
