317 *Exam: Define and Provide an Example 9/6/2016 Perception - Interpretation 3 Stages of Perception (neural energy from the brain) 1. SELECTION: Many things are going on, Select on where to pay attention. (alters how we interpret the world) a. Automatic Process – always have an impression and interpretation b. Learned Process – choose where to pay attention 2. ORGANIZATION: Organize information 3. INTERPRETATION: Interpreting the information 7 Principles of Perception (KICROAD – not in order) 1. KNOWLEDGE BASED: Interpreting information based on what you know or past experiences (constructing what we’re seeing) 2. INFERENTIAL: Filling in the blanks that have not been taken by our senses and making sense of it (learned concept) 3. CATEGORICAL: Organizing information in categories 4. RELATIONAL: Interpret objects in relation to what we know and to other objects 5. OPERATES AUTOMATICALLY: Happening automatically which tails into our survival 6. ADAPTIVE: The way we interpret things are important for our survival as species 7. DISCRETE: Favor one interpretation of an object at any given time (decide what to do about it) What is Neural Energy? Electro-chemical Language of the Brain  ELECTRO – We process information electrically in the neurons (electrical code cannot continue because neurons do not touch each other)  CHEMICAL – We process information chemically between the neurons Extracellular Structure of Neurons (D-CB-A – in order)  DENDRITES: Receiving information (Branches) Intracellular  CELL BODY/SOMA: Decision is made in CELL FIRING  AXON: Sending information NEURONS  Neurons are either FIRING or NOT  Neuron is a Membrane that exists in a FLUID ENVIRONMENT that serves as a boundary from the outside and inside the cell o Extracellular fluid (outside) o Intracellular fluid (inside)  S: particles that carry a charge (Positive and Negative charges)  Sodium: Na+  Potassium: K+  Electrical Event = Movement of Charge (intracellular vs. extracellular fluids) o POTENTIAL: Separation of Charge of different environment (intracellular vs. extracellular fluids)  Resting Potential: No movement of Charge – Cell is at rest  Na+ are concentrated outside of cell  K+ are concentrated inside of cell  Resting Potential = -70mV (millivolts) Stable Potential  Inside is more negative than outside  Membrane’s permeability is low – but allows some ions to move through  IN ORDER TO HAVE AN ACTION POTENTIAL (EXCITES US!) o UNEQUAL DISTRIBUTION OF IONS o SEMI-PERMEABLE MEMBRANE  Action Potential: Movement of Charge – “Firing” of Cell (communication is occurring)  Starts in Cell body  All of None Potential – Occurs with all strength or not o THRESHOLD HAS TO MET - “TRIGGERED” o MEMBRANE’S PERMEABILITY SHIFTS TOWARDS Na+ (Na+ channels open) o Na+ INFLUX – inside the cell o MEMBRANE’S PERMEABILITY SHIFTS TOWARDS K+ (K+ channels open) o K+ EFFLUX – leave the cell o Na+/K+ PUMP – to reset the cell back to RP  RP = -70mV 317  AP= -70mV/+40mV/-70mV  RP= -70mV  Stereotype events that happens the same way in each individual neuron  2 forces of ION movement: Concentration Gradients  Diffusion: tendency of ions to move from higher to lower concentration gradient (Na+: independent)  Electrostatic Pressure/Electrical Gradient: Like charges repel and opposite charges attract (Na+ attracted to negative charge of cell – K+ repelled by Na+ charge inside the cell then in comes out) o WHY DOES Na+ RUSH IN THE CELL? (Concentration gradient and electrical Gradient) o WHY DOES K+ MOVE? o COMPARE AND CONTRAST SENSTION & PERCEPTION  Automatic  How we explore the outside world  Happens before Cognition  Sensation: taking information & biology  Perception: making sense of the information & knowledge
