Bridging the gap between learning and memory
This thesis uses a fusion of recognition memory and implicit learning methods to investigate performance based on implicit learning. A series of experiments exposed participants to a study list composed of natural words that conform to a conjunctive rule-set involving the frequency and the …

Learning and memory in chaotic spiking neural models
… to initial conditions, space filling, control and synchronization. Biological research suggests that chaos plays an important role in carrying out information processing tasks in human brains. Also, great interest has been given recently to spiking neural networks (SNNs). Moreover, research in …

Dopamine and the Temporal Dependence of Learning and Memory
… largely influenced by the seeking out of rewards and avoidance of punishments. Positive or negative reinforcements, like a food reward or painful shock, impart meaningful valence onto sensory cues in the animal's environment. The ability of animals to form associations between a sensory cue and a …

The Role of Rac1 in Synaptic Plasticity, Learning and Memory
During the process of learning and memory, neuronal synapses undergo changes involving gene expression, protein synthesis, and cytoarchitectural remodeling, referred to as synaptic plasticity. Changes in the morphology of synapses are necessary for learning and memory storage, and require the …

Effects of Trypanosoma brucei brucei on spatial learning and memory
… African disease caused by trypanosome parasites and transmitted through tsetse flies. The HAT is clinically defined by two diagnostic stages, commencing with an early-stage also known as the haemolymphatic stage where parasites appear to be localised in the blood and lymphatic systems, then a …

Anterior Cingulate Function Across Multiple-Time Scales Shapes Learning and Memory
<p>We are constantly learning from our everyday experiences about the people we are with, the things we do,where we are, and how we feel. If deemed significant enough,we may choose to remember what we learn for the rest of our lives.For my doctoral work, I studied how a part of the neocortex, the …

Learning and memory systems supporting decision making in the human brain
… we have learned. In the brain, two prominent learning systems have been identified and each is likely to guide decisions in different ways. Research on decision making has primarily focused on a reward learning system in the striatum. These studies have illuminated the how repeated choices and …

Biologically inspired computational neural models for motivated behavior, learning, and memory
The fields of artificial intelligence (AI) and machine learning have vastly expanded in the past decade, with a variety of modern applications, ranging from computer vision to language processing and medical diagnostics. While the majority of AI applications involve data classification, detection, …

The role of ras signaling associative learning and memory in Drosophila
… such as cell proliferation, differentiation, and survival. Recent studies also suggest roles of Ras in neuronal plasticity. I investigated the role of Ras in associative learning and memory in Drosophila. Flies carrying hypomorphic ras mutations were impaired in memory, with normal learning …

The effects of an acute flurothyl seizure on associative learning and memory.
… have demonstrated impairment of spatial learning and memory in both neonatal and adult rats. However, most studies focused on inducing several seizures and much later examining learning and memory. The impact of a single acute seizure on learning and memory has not been investigated in …

The Effects of Aging on Associative Learning and Memory Retrieval in Causal Judgment
<p>Research has shown that detecting and judging causal relationships requires associative learning and memory. Retrospective revaluation of causal cues requires associative memory (Aitken, Larkin, & Dickinson, 2001) to bind multiple cues together and use these associations to retrieve unseen cues …

The effects of cholinergic and dopaminergic neurons on hippocampal learning and memory processes
Dysfunction of cholinergic and dopaminergic systems has been implicated in memory function de cits that are core pathology and associated features of several neurological disorders. However, in order to develop more effective treatments, it is crucial to better understand how different aspects of …

Investigation of the role of neuroserpin in neurite outgrowth and learning and memory
… serpin, that is expressed in the nervous system and inhibits the protease tissue plasminogen activator (tPA). Neuroserpin has been shown to play a role in neurite outgrowth but con icting results have been reported. Neuroserpin has also been proposed to play a role in learning and memory but …
