Presentation Transcript

  1. Basic Neuro Anatomy – Part IINeurotrasmiters Dr. G.Mathan Assistant Professor

  2. Synapses

  3. Neurotransmitters

  4. Withdrawal Reflex Muscles do not receive direct inhibitory input; motor neurons are inhibited in the spinal cord = less neurotransmitter release, not active inhibition of contraction

  5. Language and speech • Broca’s area – located at left frontal lobe and is part of the primary motor cortex that controls muscles in the face • Wernicke’s area – posterior portion of the temporal lobe that controls comprehension and generation of speech • Frontal & temporal areas become active when meaning must be attached to words (ex. ~ a person generates verbs to go with nouns) • Damage in this spot abolishes the ability to comprehend speech, but left speech generation intact

  6. Acknowledgement • The Presentation is being used for educational and non commercial purpose • Thanks are due to all those original contributors and entities whose pictures • used for making this presentation.
