Book Synopsis Post-Lesion Neural Plasticity by : Hans Flohr
Download or read book Post-Lesion Neural Plasticity written by Hans Flohr and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neural networks are not rigidly wired but rather highly plastic structures, the functional architecture of which can be actively reorganized in response to external or internal events. Lesions of such networks induce plastic processes which in time may lead to a recovery of the initially disrupted function. This type of neural plasticity is the main focus of the book, which presents a broad spectrum of experimental paradigms for lesion-induced plasticity as in the spinal cord, the vestibular, oculomotor, visual and olfactory system, the cerebellum and the cerebral cortex, including recent methodological developments. Concepts and perspectives in understanding neural plasticity are reported in reviews and original research reports and are thoroughly discussed.

Book Synopsis Vision: From Neurons to Cognition by : C. Casanova
Download or read book Vision: From Neurons to Cognition written by C. Casanova and published by Gulf Professional Publishing. This book was released on 2001-10-25 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Internationally renowned researchers discuss how the various parts of the brain process and integrate visual signals, providing up to date original findings, reviews, and theoretical proposals on visual processing. This book addresses the basic mechanisms of visual perception as well as issues such as neuronal plasticity, functional reorganization and recovery, residual vision, and sensory substitution. Knowledge of the basic mechanisms by which our brain can analyze, reconstruct, and interpret images in the external world is of fundamental importance for our capacity to understand the nature and causes of visual deficits, such as those resulting from ischemia, abnormal development, neuro-degenerative disorders, and normal aging. It is also essential to our goal of developing better therapeutic strategies, such as early diagnosis, visual training, behavioral rehabilitation of visual functions, and visual implants.

Book Synopsis Training-induced Plasticity in the Visual Cortex of Adult Rats Following Visual Discrimination Learning by : Audrey Marion Hager
Download or read book Training-induced Plasticity in the Visual Cortex of Adult Rats Following Visual Discrimination Learning written by Audrey Marion Hager and published by . This book was released on 2008 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synaptic plasticity plays a key role in processes of learning and memory. Long-term potentiation (LTP) is a relatively stable enhancement of synaptic transmission following specific patterns of electrical stimulation. Some types of learning (e.g. motor learning, fear conditioning) result in LTP-like changes at synapses. However, no studies have examined LTP-like plasticity in the visual cortex as a result of visual discrimination learning. A visual discrimination task was used to examine changes in LTP in the primary visual cortex (V1) of adult rats. Rats were placed in a Y-shaped water maze and required to swim to one choice arm containing a hidden platform. Distinct visual cues indicated the presence (CS+) and absence (CS- ) of the platform. Rats learned to reliably discriminate the visual cues to successfully navigate the maze. Control rats received the same procedure, but the visual cues did not have a predictive relation with the platform. Following training, trained, control, and task-naïve rats were anesthetized and visual evoked potentials (VEPs) in V1 were recorded in response to CS+, CS-, and novel stimuli. Results indicate that, in both task-naïve and control animals, all visual stimuli elicit VEPs of similar (p> 0.05) amplitude. In contrast, trained animals show significantly larger amplitude VEPs to stimuli encountered during training relative to novel stimuli, regardless of whether stimuli act as CS+ or CS-. In addition, trained animals show 71% and controls 47% potentiation (p

Book Synopsis Modification of Visual Evoked Potentials of the Rabbit During Attentive Behavior by : John Wilfred Urschel
Download or read book Modification of Visual Evoked Potentials of the Rabbit During Attentive Behavior written by John Wilfred Urschel and published by . This book was released on 1965 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual evoked potentials were investigated in a total of 16 New Zealand white, unanesthetized, partially restrained, rabbits under conditions which in humans would be likely to produce changes in "attention". The evoked potentials were recorded from the lateral geniculate body and visual cortex by means of chronically implanted bipolar stainless steel electrodes and stainless steel cortical screws. In one half of the animals the visual evoked, potentials were elicited by a peripheral visual stimulus (flash of light), while in the other half of the animals the visual evoked potentials were elicited by a central stimulus (submaximal electrical stimulation to the optic chiasma). In one experiment designed to investigate the "distraction" phenomenon these stimuli were presented under three different conditions; auditory distraction condition (clicks preceded the potential evoking stimulus), visual distraction condition (flickering light preceded the potential evoking stimulus), and control conditions (stimulus alone). The "attention" phenomenon was investigated by pairing the stimulus which produced the evoked potential with a noxious stimulus (white noise). The evoked potentials were displayed on a Single-Beam cathode ray storage oscilloscope for amplitude measurement. Following the experiment the animals were perfused and the electrode sites were verified histologically. A depression of visual evoked potentials was observed when either an auditory or visual distracting stimulus preceded the stimulus which produced the evoked potential (flash or optic chiasma stimulation). When the animal was made to "attend" to the stimulus which produced the visual evoked potential an enhancement of the evoked potentials was observed. The results provide evidence which suggests that peripheral mechanisms, such as eye movement, and closing of the eyelid, etc., does not play an important role in the processes involved in the phenomena of "distraction" and "attention". Evidence has been obtained which suggests a greater likelihood that the processes involved, are controlled by a specific sensory filtering mechanism which operates via centrifugal fibers in the visual pathway. The results also provide indirect evidence which suggests that if centrifugal fibers terminate in the retina they do not appear to play an important role in these phenomena.
