Home Glossary About the Book. A-delta fiber An intermediate-sized, myelinated sensory nerve fiber that transmits pain and temperature signals. Mathematically, acceleration is the derivative of velocity. In words, linear acceleration indicates a change in linear velocity; angular acceleration indicates a change in angular velocity.
Very few neurons are involved in the basic startle reflex, which can also be affected by emotional state. Besides our sense of equilibrium, other active human senses include vision and touch.
If light A and light B are both reflected from a surface to the eye, in the perception of color the effects of those two lights add together. More light is scattered when we look through more atmosphere. Thus, more distant objects are subject to more scatter and appear fainter, bluer, and less distinct. Compare efferent fiber. Passive sensing would rely exclusively on such sensory inflow, providing a traditional view of sensation.
See also afferent fiber, sensation and perception wolfe 4th edition pdf download. AMD gradually destroys sharp central vision, making it difficult to read, drive, and recognize faces. There are two forms of AMD: wet and dry.
Agnosia is typically due to brain damage. Also known as lazy eye. Amplitude is perceived as loudness. This complex is critically involved in the unique emotional and associative properties of olfactory cognition, sensation and perception wolfe 4th edition pdf download. Mathematically, the integral of angular acceleration is angular velocity, and the integral of angular velocity is angular displacement.
Angular acceleration, angular velocity, and angular displacement all mathematically represent angular motion. Anomia is typically due to brain damage. Symptoms include difficulty focusing attention as well as problems controlling behavior. To deal with the impossibility of handling all inputs at once, the nervous system has evolved mechanisms that are able to bias processing to a subset of things, places, ideas, or moments in time. Azimuth is measured in degrees, with 0 degrees being straight ahead.
The angle increases clockwise toward the right, with degrees being directly behind. B balance system The sensory systems, neural processes, and muscles that contribute to postural control. Specific components include the vestibular organs, kinesthesis, vestibulo-spinal pathways, skeletal bones, sensation and perception wolfe 4th edition pdf download, and postural control muscles. Basal cells are the precursor cells to olfactory sensory neurons.
Bayesian approach A way of formalizing the idea that sensation and perception wolfe 4th edition pdf download perception is a combination of the current stimulus and our knowledge about the conditions of the world—what is and is not likely to occur. When a different scent is presented to each nostril simultaneously, we perceive each scent to be alternating back and forth with the other, and not a blend of the two scents.
Stereopsis is the primary example in humans, but convergence and the ability of two eyes to see more of an object than one eye sees are also binocular depth cues. Disparity is the basis for stereopsis, a vivid perception of the three-dimensionality of the world that is not available with monocular vision. C C fiber A narrow-diameter, unmyelinated sensory nerve fiber that transmits pain and temperature signals.
C tactile CT afferent A narrow-diameter, unmyelinated sensory nerve fiber that transmits signals from pleasant touch. If the gist, sensation and perception wolfe 4th edition pdf download, or meaning, of the scene is not altered, quite large changes can pass unnoticed. The chorda tympani exits the tongue with the lingual branch of the trigeminal nerve cranial nerve V and then passes through the middle ear on its way to the brain.
The receptor sites for odorant molecules are on the cilia, which are the first structures involved in olfactory signal transduction. Circumvallate papillae are moundlike structures, each surrounded by a trench like a moat.
These papillae are much larger than fungiform papillae. Those discriminations are different from the norm—that is, anomalous. Neurons within a single column tend to have similar receptive fields and similar orientation preferences. The comparator compares the image motion signal with the eye motion signal and can compensate for the image changes caused by the eye movement.
Cone monochromats are truly color-blind. This is one of several constraints that have been proposed as helpful in solving the correspondence problem.
For example, points to the left of fixation are contralesional to damage in the right hemisphere of the brain. Convergence reduces the disparity of that feature to zero or nearly zero. In binocular vision, the problem of figuring out which bit of the image in the left eye should be matched with which bit in the right eye. The problem is particularly vexing when the images consist of thousands of similar features, like dots in random dot stereograms.
In motion detection, the problem faced by the motion detection system of knowing which feature in frame 2 corresponds to a particular feature in frame 1. The two foveas are also corresponding points.
The axons from the olfactory sensory neurons pass through the tiny holes of the cribriform plate to enter the brain. If the internal response is above criterion, the observer gives one response e.
Below criterion, the observer gives another response e. Critical periods are proposed for the development of binocular vision and development of a first human language. Cross-adaptation is presumed to occur because the components of the odors or the odorants in question share one or more olfactory receptors for their transduction, but sensation and perception wolfe 4th edition pdf download order in which odorants are presented also plays a role.
This ability allows insight into sensory differences. For example, a listener might adjust the brightness of a light until it matches the loudness of a tone.
The term crossed is used because images of objects located in front of the horopter appear to be displaced to the left in the right eye, and to the right in the left eye. Cues can be valid giving correct informationinvalid incorrector neutral uninformative. Cyclopean Referring to stimuli that are defined by binocular disparity alone.
D decay The part of a sound during which amplitude decreases offset. Decibels define the difference between two sounds as the ratio between two sound pressures.
Each sound pressure ratio equals 20 dB, and a ratio equals 40 dB. Different from binocular presentation, which could involve both eyes looking at a single stimulus. It is equal to the reciprocal sensation and perception wolfe 4th edition pdf download the focal length, in meters. Divergence reduces the disparity of that feature to zero or nearly zero. E ear canal The canal that conducts sound vibrations from the pinna to the tympanic membrane and prevents damage to the tympanic membrane.
A common example is motor commands that regulate muscle contraction. Compare afferent fiber. The entorhinal cortex also receives direct projections from olfactory regions. At the subordinate level, the object might be more specifically named e.
Euclidean Referring to the geometry of the world, so named in honor of Euclid, the ancient Greek geometer of the third century BCE. In Euclidean geometry, parallel lines remain parallel as they are extended in space, objects maintain the same size and shape as they move around in space, the internal angles of a triangle always add to degrees, and so forth. F familiar size A depth cue based on knowledge of the typical size of objects like humans or pennies.
Filiform papillae have no taste function. The focus of expansion is one aspect of optic flow. Foliate papillae are located on the rear of the tongue lateral to the circumvallate papillae, where the tongue attaches to the mouth.
Formants are specified by their center frequency and are denoted by integers that increase with relative frequency. Fourier analysis A mathematical procedure by which any signal can be separated into component sine waves at different frequencies. Combining these sine waves will reproduce the original signal. It is the portion of the retina that produces the highest visual acuity and serves as the point sensation and perception wolfe 4th edition pdf download fixation.
Frequency is perceived as pitch. Activated neurons provoke increased blood flow, sensation and perception wolfe 4th edition pdf download, which can be quantified by measuring changes in the response of oxygenated and deoxygenated blood to strong magnetic fields. Taste buds an average of six per papilla are buried in the surface, sensation and perception wolfe 4th edition pdf download.
G G protein—coupled receptor GPCR Any of the class of receptors that are present on the surface of olfactory sensory neurons. Gestalt grouping rules A set of rules describing which elements in an image will appear to group together.
The original list was assembled by members of the Gestalt school of thought. Each OSN converges onto two glomeruli one medial, one lateral. They comprise an extensive network of inhibitory neurons, integrate input from all the earlier projections, and are thought to be the basis of specific odorant identification.
H hair cell Any cell that has stereocilia for transducing mechanical movement in the inner ear into neural activity sent to the brain; some hair cells also receive inputs from the brain. One hertz equals one cycle per second. The surface of zero disparity. I illuminant The light that illuminates a surface. Also called insula or gustatory cortex.
This general law also applies to optics and other forms of energy. J just noticeable difference JND or difference threshold The smallest detectable difference between two stimuli, or the minimum change in a stimulus that enables it to be correctly judged as different from a reference stimulus. They are a mixture of excitatory and inhibitory cells and respond to a wide range of odorants. The selectivity of neurons to specific odorants increases in a gradient from the surface of the olfactory bulb to the deeper layers.
K kinesthesia Perception of the position and movement of our limbs in space.
