Recent studies have also led to the surprising insight that skin cells might transduce temperature and touch. To break the code underlying somatosensation, we must therefore understand how the skin's sensory functions are divided among signalling molecules and cell types.Lumpkin...
Animals constantly receive various sensory stimuli, such as odours, sounds, light and touch, from the surrounding environment. These sensory inputs are essential for animals to search for food and avoid predators, but they also affect their physiological status, and may cause diseases such as cance...
Below, we discuss how the chemical information is encoded and processed at the first central relay of the olfactory system, the mainolfactory bulb, as well as the functions of the bulbarneural circuitsthat are relevant for triggering specific behavioral responses. In addition to the main olfactory...
Visual and Audition In this final module, we will continue discussing the senses focusing on vision and audition. At the end of the lesson, you will be able to describe the parts of the eye and parts of the retina. We will explain how receptor functions work, describe how to explain opti...
Sensory Functions Thesensory neuronscan detect a wide variety of stimuli. The signals pass upwards to the brain along the nerves and reach neurons in thecentral nervous system(hence calledafferentorascending pathways; seeCh. 2). The sensory stimuli can be of two types –special sensesare vision...
As the brain matures, the emotional andsensory areasof the brain develop based upon the quality of attachment. WikiMatrix The first areas of the brain to be pruned are those involving primary functions, such as motor andsensory areas.
s communicating with subcortical regions deep in our brain. The frontal cortex, a large area behind the forehead, is the most recently evolved part of the brain. It is larger in humans than in other primates and is critical for many complex human functions such as language and goal setting....
general rule, psychophysicists who study crossmodal matching have concerned themselves primarily with determining precise quantitative measures of intersensory equivalence; their purpose is usually to test theoretical predictions made from psychophysical functions (which relate judgments of sensory magnitudes to...

of many vertebrate animals and is composed of folds of nerve cells and fibers. The cerebral cortex is responsible for higher functions of the nervous system, including voluntary activity and the senses of hearing, vision, and touch. In humans, it is the center of learning, language, and ...
