Ch. 2 Neuroscience and behavior 10 Everything psychological is simultaneously biological. It?s your brain not your heart that falls in love. (Discredited Aristotle mind in heart) Early 1800s Gall invented phrenology that bumps on head reveal our mental abilities. Biological Psychology- a branch of psychology concerned with the links btw biology and behavior. Sect. 1 Neural Communication Bio-psycho-social systems. Human brains are complex they follow principles govern all the animal world.

Ch 50. Sensory and Motor Mechanisms 50.1 ? sensory receptors transduce stimuli energy and transmit signals to the central nervous system by changing membrane potential. Reflex= simplest response circuit Star nosed mole that tactile ( touch) sensors on nose. Sensory Pathways have 4 functions: Sensory reception, transduction, transmission, perception Sensory reception- detection of a stimulus by sensory cells. Specialized nerurons or epithelial cells Exitst signally or in organs like eyes and ears Sensory receptor- descres a sensory cell or organ and he subcellular structure that interacts directly with simuli Detect stimuli OUTside of body like heat, light, and pressure, and chemicals. Inside body include body position, blood pressure, etc

An Overview Of Nervous System Nervous systems perform the three overlapping functions of sensory input integration motor output CNS Brain Spinal cord PNS Sensory (input) Signals from external environment Signals from skin, tendons, and muscles Signals from internal organs Motor (output) Somatic division (control of skeletal muscle) Autonomic division (autonomic control of smooth muscle, cardiac muscle, and glands) Parasympathetic Sympathetic Endocrine (Hormone) *Video by bozemanbiology via YouTube Peripheral nervous system (PNS). Sensory receptors a responsive to external and internal stimuli. Such sensory input is conveyed to integration centers. Where in the input is interpreted an associated with a response.
