Presentation Transcript

  1. Do Now – Prep for Notecards • Write the following words in your notebooks and include: • the definition, • something in your own words, • a picture, diagram, or step-by-step process • Neuron • Dendrites • Cell Body/Soma • Axon • Myelin Sheath • Node of Ranvier • Axon Terminals • Synapse • Neurotransmitters • Synaptic Vesicle • Synaptic Gap • Resting Potential • Action Potential • Threshold • Refractory Period • Nerve • Nervous System • For this notecard, include a hierarchy or concept mapinstead ofthe picture

  2. Agenda • Do Now • Review • Intro to the Brain • Homework: • Notecards • I would get started on these tonight because tomorrow will bring many readings. There will also be a list on Wednesday, but it will be long. • NO listed definitions on sheets of paper. • They will be due Wednesday, 10/9 (NEXT WEEK) • If you did extra credit, you need to tell me where to allocate the points. • Remember: You cannot get extra credit if you are missing assignments (DNQs do not count).

  3. Review:The Endocrine System& Brain Research Technology Today, I will be able to… Discuss the effect of the endocrine system on behavior. Recount historic and contemporary research strategies and technologies that support research (e.g., imaging techniques)

  4. The Endocrine System • Hormones – Chemicals that travel through the bloodstream. • Endocrine System – System of glands that secrete hormones. • Glands: • Hypothalamus • Pituitary gland • Pineal Gland

  5. The Endocrine System • Hormones – Chemicals that travel through the bloodstream. • Endocrine System – System of glands that secrete hormones. • Glands: • Hypothalamus • Pituitary gland • Pineal Gland • Thyroid Gland

  6. The Endocrine System • Hormones – Chemicals that travel through the bloodstream. • Endocrine System – System of glands that secrete hormones. • Glands: • Hypothalamus • Pituitary gland • Pineal Gland • Thyroid Gland • Adrenal Glands • Pancreas

  7. The Endocrine System • Hormones – Chemicals that travel through the bloodstream. • Endocrine System – System of glands that secrete hormones. • Glands: • Hypothalamus • Pituitary gland • Pineal Gland • Thyroid Gland • Adrenal Glands • Pancreas • Testis • Ovary

  8. Examples of Hormones • Epinephrine (Adrenaline) • Secreted by adrenal glands • Fight or flight response • Melatonin • Secreted by pineal gland • Regulates sleep • Ghrelin • Secreted by stomach • Stimulates appetite • Growth hormone (GH) • Secreted by pituitary gland • Stimulates growth and cell reproduction • Insulin • Produced by pancreas • Limits amount of glucose in blood https://www.youtube.com/watch?v=-drpViV5LSw • Testosterone • Secreted by testes • Involved in muscle growth, increased bone density, formation of male sexual organs • Estrogen • Secreted by ovaries • Reduced muscle mass, increased fat deposition, increased breast cancer risk • Oxytocin • Secreted by pituitary gland • Involved in release of breast milk, orgasm, trust • Prolactin • Secreted by pituitary and uterus • Involved in milk production • Progesterone • Secreted by ovaries and placenta • Supports pregnancy

  9. Brain Scanning Technology • EEG (electroencephalogram) • PET (positron emission tomography) & CT (computer tomography) • MRI (magnetic resonance imaging) • fMRI (functional magnetic resonance imaging) • Lesions / Electrical Stimulation • Transcranial MagneticStimulation • What do the machines look like? • What does the data look like? • What do you use it to look at? • What are its strengths? What are its weaknesses?

  10. Review:Neurons Today, I will be able to… Identify basic processes and systems in the biological bases of behavior, including parts of the neuron and the process of transmission of a signal between neurons.

  11. Neurons: Neural Anatomy Cell Body / Soma Axon Myelin Sheath Dendrites Node of Ranvier Axon Terminals

  12. Neurons: Neural Anatomy Cell Body / Soma Dendrites Synapse Dendrites Axon Axon Terminals Post-Synaptic Neuron Pre-Synaptic Neuron

  13. Neurons: Synaptic Anatomy • Synapse • Synaptic Gap • Synaptic Knob • Synaptic Vesicle • Neurotransmitters • Receptor Sites Post-Synaptic Neuron Pre-Synaptic Neuron AxonTerminal Dendrite

  18. Neural Transmission: Action Potential • Resting Potential • Threshold • Action Potential • Refractory Period • Selectively Permeable • Ion Channels • Depolarization

  19. Neural Transmission: Action Potential • Resting Potential • Threshold • Action Potential • Refractory Period • Selectively Permeable • Ion Channels • Depolarization • Sodium-Potassium Pump • 3 Na out for every 2 K in • Negative charge inside the axon

  20. Neural Transmission: Action Potential • Resting Potential • Threshold • Action Potential • Refractory Period • Selectively Permeable • Ion Channels • Depolarization • Sodium-Potassium Pump • 3 Na out for every 2 K in • Negative charge inside the axon

  21. Neural Transmission: Action Potential • Resting Potential • Threshold • Action Potential • Refractory Period • Selectively Permeable • Ion Channels • Depolarization

  22. Neural Transmission: Synaptic Transmission • Synapse • Synaptic Gap • Synaptic Knob • Synaptic Vesicle • Neurotransmitters • Receptor Sites • Excitatory / Inhibitory AxonTerminal Dendrite

  23. Neural Transmission: Synaptic Transmission • Synapse • Synaptic Gap • Synaptic Knob • Synaptic Vesicle • Neurotransmitters • Receptor Sites • Excitatory / Inhibitory AxonTerminal Dendrite

  24. Take a breath. • If you were a n00b, that would have been a lot of information. • For you, this is review. • If this is NOT review for you, you need to make an appointment with me so you can catch up.

  25. The Nervous System Today, I will be able to… Describe the nervous system and its subdivisions and functions Central and peripheral nervous system Major brain regions, lobes, and cortical areas

  26. When you bundle neurons together…

  27. Nervous System

  28. Nervous System - PNS Somatic Nervous System Autonomic Nervous System Sympathetic Division Fight or flight response Heart rate and respiration increases Digestion is halted Parasympathetic Division Relaxation Heart rate and respiration decreases Digestion resumes • Afferent nerves • Sensory neurons • Carry information toward a central point (i.e., the brain and spinal cord) • Efferent nerves • Motor neurons • Carry information away from the brain and spinal cord

  29. Nervous System - CNS • Spinal Cord
