Housekeeping you are responsible for what appears in slides, what she says in lecture, and what is covered in discussion section look at office hours Post questions on discussion board, not via email! midterm exam May 2 (multiple choice) Final exam: not cumulative. June 7 every discussion section starts with quiz quizzes are on course lecture material of previous week you can drop one quiz you can do 2 hours in SONA for extra credit This course lecture slides are uploaded using neuroscience to study human behavior what is this course about o 'the scientific study of the biology of behavior o psychobiology, behavior biology, behavioral neuroscience o how does the brain control behavior we will explore the ways in which brain structure and action produce behavior o how does behavior alter the brain we will explore the ways in which behavior modified brain structure and action your brain o 86 billion neurons make ten trillion synaptic o brain has no pain receptors this is why we can study epilepsy (open brain) o axons allow one cell to communicate with the next o Giraffe: neurons in brain send axon projections down. Axons can be fifteen feet long. o 25 watts of power o speed of neural conduction nerve impulses travel 220 miles per hour o all this obtained through experimentation Integrative approach: Spanning multiple disciplines o neuroanatomy: structure of nervous system o neurochemistry: chemical bases of neural activity o neuroendocrinology: interactions between the nervous system and the endocrine system o neuropathology: nervous system disorders o pharmacology: effects of drugs on neuronal activity o neurophysiology: functions and activities of the nervous system (looking specifically at neurons and circuits of neurons communicate information) o Explore the relationship between the physical matter of your body (your nervous system and its signals) and how you think, act and behave... circle of signals social level: individuals behaving in social interaction > organ level: brain spinal cord, peripheral nerves, and eyes > neural system level: eyes and visual brain regions > brain region level: visual cortex > circuit level: local neural circuit> cellular level: single neuron> synaptic level The Nervous System the nervous has 3 basic functions o collect information o process information o generate behavior neurons in the CNS process info and generate behavior sensory neurons of the PNS collect information PNS motor neurons relay behavioral plan to muscles Case Study o Face Blindness prosopagnosia blindness to face face appears to be jumble of individual facial parts all other aspects of visual processing and intellectual function are intact can be acquired (selective brain damage) or congenital (developmental) location of damage: the fusiform gyrus Case Study o impervious to pain o highly intelligent woman who has never felt pain o painful experiences were not accompanied by normal physiological responses, change in blood pressure, respiration, heart rate o advantages you would never feel pain, cough or sneeze, cry from injury experience, brain freeze o rare disorder o causes genetic defect?: disrupted synthesis of sodium ion channels in parts of the brain peripheral nervous system?: connects the brain and spinal cord to muscles and to cells that detect sensations Case Study o koraskoff's syndrome o severe anterograde amnesia: unable to form new memories, Jimmie, a 49 year old believed he was 19 years of age, o all other cognitive abilities intact o vitamin B1 (thiamine deficiency) helps brain cells produce energy from sugar biochemical disruption affecting signal transduction leading to cell death (thalamus and mammillary bodies) o location of damage: medial diencephalon Case Study o conflicted by a splitbrain o suffered throughout childhood from intractable epilepsy (severe seizures0 o treated Definitely look at class slides and memorize The Brain The human brain is 3lbs. The brain of a sperm whale is 17lbs composed of 78% water, 10% lipids, 8% protein, 1% carbohydrate, 2% soluble organic substances, 1% inorganic salts cells of the nervous system o neurons specialized cells that are capable of sending and receiving chemical signals about 86 billion neurons in the human brain o there are different structural classes multipolar bipolar monopolar o polarity: refers to the number of processes (out growths) coming from the cell body (refers to dendrites and axon) Neural Anatomy o neurons are information processors they collect information, process/integrate info and transmit info to other neurons o dendrites: collect info o cell body (soma): integrates info o axon: integrates and transmits o axon terminals: transmit info o see diagram on slide and memorize parts of a neuron o the soma/cell body nucleus contains DNA (genetic code) enzymes to synthesize proteins, receptors and neurotransmitters enzymes to provide energy The soma o enzymes to synthesize o cell body same as every other cell o nucleus, ER, ribosomes, Golgi, microtubules, mitochondria the dendrites o receive info from other neurons o single branch can have multiple protrusions o spine structure isn't static o spine comes out the axons o info combines to make signal o some neurons get one signal about shape, and about color o see slide about synaptic and C. Elegans o connectome: wiring of neurons o aplysia rat o name: rattus norvegiens o rat brain structured like ours o clear division of CNS PNS o distinct DNA area (brain) o neurons organized into complex and distributed circuits brain anatomy and behavioral complexity o cerebellum= motor control o cerebellum of bird is as big as their cortex
