Learning Objective • Identify the parts of the neuron and describe the basic process of neural transmission. Neural Communication Neurobiologists and other investigators understand that humans and animals operate similarly when processing information. Note the similarities in the above brain regions, which are all engaged in information processing. Biological psychologists • Study the links between biological activity and psychological events • Humans are biopsychosocial systems.

For Wednesday Lesson Nervous System Endocrine System Psych Sim Chapter 2 – Brain and Behavior – Hemispheric Specialization Journal Prompt 10/3 • 2.1 Describe how the endocrine glands are linked to the nervous system • 2.2 Describe the effects of hormones on behavior and mental processes • 2.3 Describe hormone effects on the immune system • P. 59 Why is the pituitary gland called the master gland? What specific behaviors does it control? • Journal prompt: Pituitary gland • Endocrine systems • Video Clips – THE BRAIN Hormones during Brain Development – THE MIND Endorphin Receptors – THE MIND Dopamine Pathways • Review The Brain Packet The Endocrine System The Endocrine System is the body’s “slow” chemical communication system. Communication is carried out by hormones synthesized by a set of glands. Today’s Lessons 10/2 (B); 10/5 (A) Journal Prompt : Left-handedness Review of lobes and brain structures EXAM 10/8 (B); 10/9 (A) Vocabulary outline or list due at exam. (I will give a binder grade for Chapter 2 along with Chapter 3.) Journal Prompt 10/2 (B); 10/5 (A) • 1.4 Describe lateralization of brain functions. p. 80 How do two-day-old babies demonstrate tendencies to left-handedness or righthandedness? How is this determined at age 5 months? What do such findings show about the cause of left- or right-handedness? left handed/ ed ted lessons Structure of the Cortex Each brain hemisphere is divided into four lobes that are separated by prominent fissures. These lobes are the frontal lobe (forehead), parietal lobe (top to rear head), occipital lobe (back head) and temporal lobe (side of head). AP Psychology 10/6 (B); 10/7 (A) • Journal prompt: – Neurogenesis • Notes: – Having your head examined • • • • EEG PET MRI fMRI • Next class 10/8 (B); 10/9 (A) – EXAM • FRQ to follow – Chapter 2 Vocabulary outline • Journal is not due this week. I will pick it up with chapter 3. Journal prompt 10/6 (B); 10/7 (A) • Discuss the mechanisms and the importance of plasticity of the nervous system. p. 74 What scientific advances might we look forward to as the result of current research on neurogenesis? Free Response Question • Part II. Sixteen point question will be on the test. If you stub your toe, how does the impulse travel through your nervous system allowing you to pull your toe back and jump up and down in pain? Explain how this process occurs (including the process of neural transmission) using the following terms in context: • • • • • • • • Sensory neuron Peripheral nervous system Central nervous system Interneuron Motor neuron Action potential Neurotransmitter Synapse Electroencephalogram (EEG) An amplified recording of the electrical waves sweeping across the brain’s surface, measured by electrodes placed on the scalp.

PET Scan Courtesy of National Brookhaven National Laboratories PET (positron emission tomography) Scan is a visual display of brain activity that detects a radioactive form of glucose while the brain performs a given task. MRI Scan MRI (magnetic resonance imaging) uses magnetic fields and radio waves to produce computergenerated images that distinguish among MRI on dog Both photos from Daniel Weinberger, M.D., CBDB, NIMH different types of brain tissue.
