Instruction Exam 1 Chapter 2 part 2 Warmup 1 When a neuron is at its resting potential the inside of a cell is and the outside is Consequently at the action potential the inside of the cell becomes and the outside becomes 2 What specific event causes the release of chemicals into the synaptic gap 6 A Positive negative positive negative B Positive negative negative positive C negative positive negative positive D negative positive positive negative A An agonist binding to the dendrites B An action potential reaching the axon terminal C The reuptake of neurotransmitters D Excitation of the glial cells 3 Neuron A releases a neurotransmitter into the synaptic gap As a result the frequency of action potentials in Neuron B the receptor cell is reduced Which of the following neurotransmitters is most likely to have been released by Neuron A 8 A An inhibitory NT B An excitatory NT C Glutamate this is an excitatory NT in the CNS D An agonist Activity 1 Guess Who I send information from your senses to the spinal cord An example of how I am used is to relay information about a sharp pain in your finger Who am I Afferent sensory I send commands from the spinal cord to your muscles I m responsible for sending a command to pull your finger back from a painful stimulus such as a hot stove Who am I Efferent motor I connect the two types of neurons mentioned and help to coordinate the signals Who am I Interneurons 4 Together all of these neurons act together in the spinal cord to form me Who am I Reflex arc The blue are afferent sensory neurons The green are interneurons neurons The red are efferent motor neurons 1 2 3 SI Leader Ashleigh Ledet alede12 tigers lsu edu Sessions Monday 6 7 30 Allen 35 Office 39 Allen basement Wednesday 6 7 30 Allen 35 Office hours Friday 9 30 11 30 AM Activity 2 Label the four lobes of the brain Generate a clue for remembering each lobe Green Temporal lobe 2 Yellow parietal lobe contain receptors for touch taste temperature Blue frontal lobe Green temporal lobe What is responsible for complex mental processes and decision making it also contains the motor cortex Frontal lobe The parietal lobes contain the somatosensory cortex What is it responsible for Area of neurons lobes Use processing information from the skin and internal body receptors for touch temperature body position running parietal down front the the of This lobe contains the primary association cortex and the auditory association cortex and is also responsible for some aspects of language What lobe is it Temporal What is the difference between the primary and auditory cortex Primary auditory cortex processes auditory information from the ears Auditory association cortex interprets or makes sense of auditory information The occipital lobe contains the primary visual cortex and the visual association cortex What are their functions Primary visual cortex processes visual information from the eyes Visual association cortex interprets or makes sense of visual information Hemispheres Left controls right hand spoken language verbal communication written language math calculations logical though processes analysis of detail reading Right Controls non verbal communication visual spatial perception controls the left hand music and artistic processing emotional thought and recognition pattern and facial recognition Separated by corpus callosum thick band of neural fibers SI Leader Ashleigh Ledet alede12 tigers lsu edu Sessions Monday 6 7 30 Allen 35 Office 39 Allen basement Wednesday 6 7 30 Allen 35 Office hours Friday 9 30 11 30 AM Critical thinking Which parts of the brain are responsible for these disorders Where are they in the brain Describe the differences between Broca s Aphasia and Wernicke s Aphasia Association areas are the areas within each of the lobes that are responsible for making sense of all the incoming information Broca s Area located in the left frontal lobe in most people and is responsible for language production A person with damage to this area would have trouble producing the words that he or she wants to speak called Broca s aphasia Wernike s Area located in the left temporal lobe responsible for comprehension of language If this area of the brain is damaged individuals are often still able to speak fluently but their words do not make sense Activity 3 Name Pons Medulla Reticular Formation RF Cerebellum The Brain Location Hindbrain brainstem specifically Hindbrain brainstem specifically Hindbrain brainstem specifically Hindbrain Midbrain didn t put on wksheet Limbic System not specifically on wksheet segment of the brainstem that lies between the hindbrain and the forebrain consists of structures under the cortex that function memory motivation Thalamus Limbic System it s a round structure in the center of the brain Hypothalamus Below the thalamus limbic system Role Messages between the cerebellum and cortex sleep dreaming Heartbeat breathing swallowing arousal attention alertness Controls and coordinate all involuntary rapid fine motor movements movements that happen in rapid succession integrates sensory processes such as vision and hearing one area also involved in dopamine synthesis Also H omeostasis O lfaction smell M emory E motion acts as the brain s sensory switchboard relaying incoming sensory information to the appropriate sensory areas in the cortex except smell and processes it before sending it out Helps directs several maintenance activities like thirst hunger body temperature sleeping and waking sexual behavior and emotions Controls the pituitary gland SI Leader Ashleigh Ledet alede12 tigers lsu edu Sessions Monday 6 7 30 Allen 35 Office 39 Allen basement Wednesday 6 7 30 Allen 35 Office hours Friday 9 30 11 30 AM Hippocampus Limbic system located on sides kinda by ears Amygdala Cortex Limbic system two almond shaped neural clusters located near hippocampus Outermost covering of the brain consists of densely packed neurons Corticalization wrinkling increases surface area more cells can fit into the space Plays a vital role in learning and memory for facts knowledge comparison of
