It explains nervous system organization by neuron types and brain lobe functions, outlines threshold and Weber’s law, and contrasts signal detection and response bias outcomes. It also covers parasympathetic versus sympathetic pathways, brain mapping methods (EEG, PET, rCBF, MRI, fMRI, CT), sensory pathways for vision and hearing, neurotransmitter influences on behavior, and fundamentals of consciousness stages. Finally, it introduces object recognition models and key learning and memory processes like habituation.","BIOLOGY AND BEHAVIOR  \nThreshold:the minimum stimulus that causes achange in signal transduction  \nThe cerebral cortex is divided into four lobes.  \n# Organization of the Nervous System\n\nJust-noticeable difference:minimum amoun of changerequired in order for a difference to be perceived  \nThe three types of neurons in the nervous systemare motor(efferent),interneuons,and sensory(afferent).  \nLobeFunctionFrontalExecutive function,impulse control,long-term planning(prefrontal cortex),motor function (primary motor cortex),speech production(Broca's area)ParietalSensation of touch,pressure,temperature,and pain(somatosensorycortex);spatial processing,orientation,and manipulationOccipital Visual processingTemporalSound processing(auditory cortex),speech perception(Wernicke's area),memory,and emotion(limbic system)  \nWeber's law:states that the just-noticeable differencefora stimulus is proportional to the magnitude of thestimulus,and this proportion is constant over mostof the range of possible stimuli  \nThe parasympathetic branch of the autonomic systemis focused on“rest-and-digest”responses and thesympathetic branch is focused on “fight-or-flight”responses.  \nSignal detection theory:studies the effects ofnonsensory factors,such as experiences,motives,and expectations,on perception of stimuli  \nParasympathetic System  \nSubject's Response  \nCoustricts pupils  \n“No”  \n“Yes”  \nStimulates flow  \n\n| Hit   | Miss   |\n| --- | --- |\n| False  \u003Cbr>alarm   | Correct  \u003Cbr>negative   |\n\nof saliva  \nSignal  \nCoustrictsbronchi  \nPresent  \nSlowsheartbeat  \nSignal  \nand secretion  \nAbsent  \nStimulates bile  \nrelease  \nResponse bias:examined using signal detectionexperiments with four possible outcomes:hits,misses,false alarms,and correct negatives  \nContracts bladder  \nVision  \nThe eye is an organ specialized to detect light in theform of photons.  \nMethods of Mapping The Brain  \n·EEG  \n● PET  \n·rCBF  \n● MRI  \n·fMRI  \n·CT  \nInfluences on Behavior  \n\n| Behavior  \u003Cbr>Neurotransmitter   |\n| --- |\n| Acetylcholine  \u003Cbr>Voluntary muscle control,  \u003Cbr>parasympathetic nervous  \u003Cbr>system,attention,alertness   |\n| Epinephrine and  \u003Cbr>Fight-or-flight responses,  \u003Cbr>Norepinephrine  \u003Cbr>wakefulness,alertness   |\n| Dopamine  \u003Cbr>Smooth movements,postural  \u003Cbr>stability   |\n| Serotonin  \u003Cbr>Mood,sleep,eating,  \u003Cbr>dreaming   |\n| Brain “stabilization”  \u003Cbr>GABA,Glycine   |\n| Brain “excitation”  \u003Cbr>Glutamate   |\n| Endorphins  \u003Cbr>Natural painkillers   |\n\nVisual pathway:retina→optic nerve→opticchiasm→optic tracts→lateral geniculate nucleus(LGN)of thalamus→visual radiations→visualcortex  \n# Hearing and Vestibular Sense\n\nOrganization of the Brain  \n·Hindbrain:contains the cerebellum,medullaoblongata,and reticular formation  \nThe ear transduces sound waves into electricalsignals that can be interpreted by the brain.  \n·Midbrain:contains the inferior and superiorcolliculi  \n·Forebrain:contains the thalamus,hypothalamus,basal ganglia,limbic system,and cerebral cortex  \nNature vs.nurture is a debate regarding thecontributions of genetics(nature)and environment(nurture)to an individual's traits.Family,twin,andadoption studies are used to study nature vs.nurture.  \n# Parts of the Forebrain\n\n● Thalamus:relay station for sensoryinformation  \n·Hypothalamus:maintains homeostasis andintegrates with the endocrine system throughthe hypophyseal portal system that connectsit to the anterior pituitary  \nSensation vs.Perception  \nSensation is the conversion of physical stimuli intoneurological signals,while perception is the processingof sensory information to make sense of its significance.  \n·Basal ganglia:smoothens movements andhelps maintain postural stability  \nmid  \n·Sensory receptors respond to stimuli andtigger electrical signals.  \n·Cochlea:detects sound  \n·Limbic system:controls emotion and memory.Includes septal nuclei (pleasure-seeking),amygdala(fear and aggression),hippocampus(memory),and fornix(communication withinlimbic system).  \n·Utricle and saccule:detect linear a","cbCaij8I5bylorpy","https://ap.wps.com/l/cbCaij8I5bylorpy","pdf",54189640,1,24,"English","en",105,"# Organization of the Nervous System\n## Brain organization and neuron types\n## Threshold, Weber’s law, and signal detection\n## Parasympathetic vs sympathetic systems\n## Vision pathway and visual pathway\n## Methods of mapping the brain\n# Hearing and Vestibular Sense\n## Organization of the brain by regions\n# Parts of the Forebrain\n## Thalamus, hypothalamus, basal ganglia, and limbic system\n## Sensation vs perception","[{\"question\":\"How do threshold and Weber’s law relate to perception?\",\"answer\":\"Threshold is the minimum stimulus needed to trigger signal transduction.
