Presentation Transcript

  1. Thurs Sept 29 and Fri Sept 30 Objective: Students will explain imaging techniques and genetic disorders. • CBM – keep as study tool • Imaging techniques • Genetic disorders • Review videos

  2. Imaging Techniques • EEG • CAT Scan • MRI • fMRI • PET • Transcranial ultrasound

  3. Genes • Transmission by biological processes • 23 pairs of chromosomes • Gene – determines trait

  4. Chromosomal Abnormalities • Turner’s Syndrome • A baby is born with just a single X chromosome (girls) • Shortness, webbed neck and lack of ovaries and secondary sex characteristics • Klinefelter’s Syndrome • A baby is born with and extra X (XXY) (boys) • Minimal sexual development and extreme introversion • Down’s Syndrome • A baby is born with and extra chromosome on the 21st pair • Rounded face, shorter fingers, low cognitive ability

  5. Recessive Gene Disorders • Tay-Sachs Syndrome • Progressive loss of nervous function • Eventual death • Albinism • Failure to synthesize or store pigment • Abnormal nerve pathways to the brain – inability to perceive three dimensional • Phenylketonuria (PKU) • Severe, irreversible brain damage if not fed special diet for first 30 days after birth • Lacks ability to process amino acid

  6. Dominant Gene Disorders • Huntington’s Disease • Degeneration of nervous system • Forgetfulness, tremors, jerky motions • Loss of ability to talk • Personality changes

  7. Review Videos Pinky and the Brain http://www.youtube.com/watch?v=Li5nMsXg1Lk&safety_mode=true&persist_safety_mode=1&safe=active Psych files http://www.thepsychfiles.com/2008/09/episode-72-video-memorize-the-parts-of-the-brain/

  8. Review Items Neural Communication Neurons & the parts Neurotransmitters; problems resulting from neurotransmitter issues Synapse Communication between neurons Nervous System Central Peripheral Autonomic Sympathetic Parasympathetic Somatic Imaging CT Scan EEG MRI PET fMRI Brain Structures Hindbrain & parts within Midbrain & parts within Forebrain & parts within Lobes Temporal Parietal Frontal Occipital Hemispheres Strength of each Split brain operation Endocrine System Hormones & Glands Functions of each & problems resulting from imbalance of each
