Available in PDF, EPUB and Kindle. Book excerpt: The notion that learning and memory processes are highly dependent on central cholinergic neurotransmission has been widely accepted. However, studies documenting the importance of Acetylcholine (ACh) in attention have led some to suggest that attention impairments may underlie the deficits in learning and memory resulting from cholinergic disruptions. Using a visual discrimination task, I attempted to discern whether performance impairments by Scopolamine were predominantly due to the importance of muscarinic receptor integrity in attention, or memory consolidation in learning. Rats were trained in a visual discrimination task using a Y-shaped water maze apparatus. To successfully navigate to a hidden platform located in one of the two goal arms, rats learned to discriminate between 2 distinct visual cues, indicating the platform's presence (CS+) or absence (CS- ), respectively. Following task acquisition, testing continued using a combination of Regular trials (RT; both CS+ and CS- present) and Probe trials (PT; only one of the cues present). Results indicated that performance on PT was impaired due to greater task difficulty under conditions of reduced information, while Scopolamine (1 mg/kg) further impacted PT performance without affecting RTs. In a second experiment, PTs were administered with the platform present to provide reinforcement and a learning opportunity. Animals still exhibited poorer PT performance, but rapidly learned to rely on a single cue for accurate platform localization. Interestingly, this learning was not apparent under conditions of Scopolamine treatment (1 mg/kg), even though RT performance was completely unaffected. To examine experience-dependent changes in neuronal responding after visual discrimination learning, a subset of animals were anesthetised and visual evoked potentials (VEPs) in V1 and area CA1 of the hippocampus were recorded in response to CS+, CS-, and novel stimuli. In both the V1 and CA1, the VEP amplitudes elicited to familiar and novel stimuli were not significantly different. First, these experiments demonstrate the importance of the cholinergic system in sustaining visual attention and acquiring a new single-cue strategy. Furthermore, the null electrophysiology findings do not rule out the plastic response properties of the mature V1 and CA1, but remind us of the complex nature of memory encoding in the brain.

Book Synopsis The Uplift Project by : R. Robert Holson
Download or read book The Uplift Project written by R. Robert Holson and published by Xlibris Corporation. This book was released on 2016-03-04 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the author puts forward an agenda to enhance intelligence and longevity in humans, select animal species (including dogs, dolphins and elephants), and machines. This effort would extend over 1,000 years or 40 human generations. Enhancements of IQ and longevity in humans would involve both environmental and genetic improvements in membership IQ and longevity. The goal would be a mean IQ of 145 and an average longevity of 100 years in human Uplift Project members by the end of these 1,000 years. Given that Uplift Project members will probably at project outset have better than average IQ and life expectancy, this could involve as little as a two standard deviations increase in IQ (30 points) and one standard deviation increase in longevity (20 years) over these 1,000 years.The Uplift Project would also expand human, animal and machine membership not only across the planet, but to the moon, Mars, and space colonies.

Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Object Novelty Recognition, Volume 26, synthesizes the empirical and theoretical advances in the field of object recognition and memory that have occurred since the development of the spontaneous object recognition task. The book is divided into four sections, covering vision and perception of object features and attributions, definitions of concepts that are associated with object recognition, the influence of brain lesions and drugs on various memory functions and processes, and models of neuropsychiatric disorders based on spontaneous object recognition tasks. A final section covers genetic and developmental studies and gender and hormone studies. Details the brain structures and the neural circuits that underlie memory of objects, including vision and olfaction Provides a thorough description of the object novelty recognition task, variations on the basic task, and methods and techniques to help researchers avoid common pitfalls Assists researchers in understanding all aspects of object memory, conducting object novelty recognition tests, and producing reliable, reproducible results
