UNIT 4: SENSATION AND PERCEPTION Sensation: your window to the world Sensation a process by which our sensory receptors and nervous system receive and represent stimulus (or physical) energy and encode it as neural signals. Our sensory and perceptual processes work together to help us sort out complex processes Bottom-Up Processing analysis that begins with the sense receptors and works up to the brain?s integration of sensory information Top-Down Processing information processing guided by higher-level mental processes as when we construct perceptions drawing on our experience and expectations The Absolute Threshold minimum stimulation needed to detect a particular stimulus 50% of the time. It is the intensity at which we can detect a stimulus half of the time

PHRENOLOGY -Invented by Franz Gall in the early 1800?s -A theory that claimed that bumps on the skull could reveal our mental abilities and character traits The Nervous System It starts with an individual nerve cell called a NEURON Neuroanatomy Synapse Synapse How does a Neuron fire? Resting Potential: slightly negative charge Reach the threshold when enough neurotransmitters reach dendrites Go into Action Potential All-or-none response Transfer of ions across axon?s membrane causes electrical charge Neural Communication Types of Neurotransmitters Serotonin Involved in mood, sleep and wakefulness, eating, & aggressive behaviors Lack of serotonin has been linked to depression, anxiety, insomnia, OCD Norepinephrine

SEQ CHAPTER \h \r 1AP Psychology Name Unit IV: Sensation & Perception Homework Assignments Read the assigned pages of your textbook for understanding of the content. To do this you need to (1) answer the provided guided reading questions OR (2) take notes on your own. You do NOT need to do both! Module 16: pages 151-160 Explain the difference between sensation and perception. Sensation is the process where our sensory receptors and nervous system receive and represent stimulus energies from our environment. Perception is the process of organizing and interpreting sensory information, enabling s to recognize meaningful objects and events. Sensation: what the senses detect Perception: organizing and making connections

Module 9: pages 76-80 What is the main focus of biological psychology? The main focus of biological psychology are the links between biological and psychological processes. What is a neuron? A neuron is a nerve cell; the basic building block of the nervous system. Identify the parts of a neuron. Dendrite: a neuron?s bushy, branching extensions that receive messages and conduct impulses toward the cell body

A.1 Neural Development Paper 3 Topic I. Neural Tube Development a) The neural tube of embryonic chordates is formed by in folding of ectoderm followed by elongation of the tube. b) All chordates develop a dorsal nerve cord through a process called neurulation in early stages of development c) The cells located in a portion of the middle of the ectoderm (dorsally located) differentiate to form the neural plate d) The ectoderm is separated from the neural plate by the neural plate border I. Neural Tube Development-continued e) The cells of the neural plate change shape, causing the plate to bend inwards and form a groove. The border is now called the neural crest. f) The in folded neural crest closes and separates from ectoderm forming the neural tube

Doreen Pang Mrs. Trainor AP Psychology 18 October 2016 Module 5-3: Hemispheres & Split Brain Our divided brain We?ve known for over 100 years that the two sides of the brain have different purposes. Damage to the left hemisphere resulted in problems with: reading writing speaking math reasoning Around 1960 discovered that the right hemisphere had its specialties patients with severe epileptic seizures had their corpus callosum cut The corpus callosum links the two hemispheres The seizures stopped and the patients were very normal afterwards. These patients were then subject to experiments. The patient stared at the center of a screen and words or images were sent displayed to each side and thus were sent to one half of their brain Left brain

Doreen Pang Mrs. Trainor AP Psychology 10 October 2016 Module 4-3: How Neurons Communicate: The Neural Chain Specialized cells in the sensory systems of the body Can turn some energy --> action potentials Neural impulses Our brain only uses neural energy to communicate specialised cells that translate outer energy into neural impulse Receptor cells in the eye turn light into a neural impulse the brain understands. Sensory (Afferent) Nerve Carry info. from the sensory receptors to: spinal cord brain A network of cells that take thermal energy and translate into neural impulse Connect the sense organs to the brain and spinal cord. Interneurons Nerve cells in the brain and spinal cord responsible for processing information. Related to sensory input and motor output.

Doreen Pang Mrs. Trainor AP Psychology 7 October 2016 Module 4-2: Neural Communication and Neurotransmitters How Neurons Communicate Neurons are interweaved very intricately hard to see where one ends and another begins Santiago Ram?n y Cajal Concluded that individual neurons functions as independent agents within the nervous system. Charles Sherrington noticed neural impulses were taking too long to travel a neural pathway must be brief interruption in the transition Synapse the junction of Sherrington aka synaptic gap cleft Neurotransmitters when action potential reached the terminals at axon?s end triggers release of chemical messengers How Neurotransmitters Influence Us Are certain nerotrans. found only in specific places?
