Presentation Transcript

    1. 2007-2008 Nervous Systems

    3. Types of neurons

    4. Cephalization = Brain evolution

    5. Cephalization = Brain evolution

    6. Evolution of vertebrate brain

    7. Human brain

    8. Functional divisions of brain Hindbrain evolutionary older structures of the brain regulate essential autonomic & integrative functions brainstem pons medulla oblongata midbrain cerebellum thalamus, hypothalamus

    9. Brainstem The lower brain medulla oblongata pons midbrain Functions homeostasis coordination of movement conduction of impulses to higher brain centers

    10. Medulla oblongata & Pons Controls autonomic homeostatic functions heart & blood vessel activity breathing swallowing vomiting digestion Relays information to & from higher brain centers

    11. Midbrain Involved in the integration of sensory information regulation of visual reflexes regulation of auditory reflexes

    12. Reticular Formation Sleep & wakefulness produces patterns of electrical activity in the brain recorded as an ElectroEncephaloGram (EEG) most dreaming during REM (rapid eye movement) sleep

    13. Cerebrum Most highly evolved structure of mammalian brain Cerebrum divided hemispheres left = right side of body right = left side of body Corpus callosum major connection between 2 hemispheres

    14. Lateralization of Brain Function Left hemisphere language, math, logic operations, processing of serial sequences of information, visual & auditory details detailed activities required for motor control Right hemisphere pattern recognition, spatial relationships, non-verbal ideation, emotional processing, parallel processing of information

    15. Cerebrum specialization Regions of the cerebrum are specialized for different functions Lobes frontal temporal occipital parietal

    17. Limbic system

    18. Simplest Nerve Circuit

    19. Eye Blink or Pain Withdrawal Reflex
