The Athlete’s Brain: Cross-Sectional Evidence for Neural Efficiency during Cycling ExerciseThe “neural efficiency” hypothesis suggests that experts are characterized by a more efficient cortical function in cognitive tests. Although this hypothesis has been extended to a variety of movement-related tasks within the last years, it is unclear whether or not neural efficiency is present in cyclists performing endurance exercise. Therefore, this study examined brain cortical activit... ... hiện toàn bộ

Differences in Cortical Representation and Structural Connectivity of Hands and Feet between Professional Handball Players and Ballet DancersIt is known that intensive training and expertise are associated with functional and structural neuroadaptations. Most studies, however, compared experts with nonexperts; hence it is, specifically for sports, unclear whether the neuroplastic adaptations reported are sport-specific or sport-general. Here we aimed at investigating sport-specific adaptations in professional handball players a... ... hiện toàn bộ

Mechanisms of GABAergic Homeostatic PlasticityHomeostatic plasticity ensures that appropriate levels of activity are maintained through compensatory adjustments in synaptic strength and cellular excitability. For instance, excitatory glutamatergic synapses are strengthened following activity blockade and weakened following increases in spiking activity. This form of plasticity has been described in a wide array of networks at several ... ... hiện toàn bộ

Role of MicroRNA in Governing Synaptic PlasticityAlthough synaptic plasticity in neural circuits is orchestrated by an ocean of genes, molecules, and proteins, the underlying mechanisms remain poorly understood. Recently, it is well acknowledged that miRNA exerts widespread regulation over the translation and degradation of target gene in nervous system. Increasing evidence suggests that quite a few specific miRNAs play important roles i... ... hiện toàn bộ

Alterations of GABAergic Signaling in Autism Spectrum DisordersAutism spectrum disorders (ASDs) comprise a heterogeneous group of pathological conditions, mainly of genetic origin, characterized by stereotyped behavior, marked impairment in verbal and nonverbal communication, social skills, and cognition. Interestingly, in a small number of cases, ASDs are associated with single mutations in genes encoding for neuroligin-neurexin families. These are a... ... hiện toàn bộ

Brain Plasticity and Disease: A Matter of InhibitionOne major goal in Neuroscience is the development of strategies promoting neural plasticity in the adult central nervous system, when functional recovery from brain disease and injury is limited. New evidence has underscored a pivotal role for cortical inhibitory circuitries in regulating plasticity both during development and in adulthood. This paper summarizes recent findings showing tha... ... hiện toàn bộ

Endocannabinoid System and Synaptic Plasticity: Implications for Emotional ResponsesThe endocannabinoid system has been involved in the regulation of anxiety, and proposed as an inhibitory modulator of neuronal, behavioral and adrenocortical responses to stressful stimuli. Brain regions such as the amygdala, hippocampus and cortex, which are directly involved in the regulation of emotional behavior, contain high densities of cannabinoid CB1 receptors. Mutant mice lacking ... ... hiện toàn bộ

The Current Status of Somatostatin-Interneurons in Inhibitory Control of Brain Function and PlasticityThe mammalian neocortex contains many distinct inhibitory neuronal populations to balance excitatory neurotransmission. A correct excitation/inhibition equilibrium is crucial for normal brain development, functioning, and controlling lifelong cortical plasticity. Knowledge about how the inhibitory network contributes to brain plasticity however remains incomplete. Somatostatin- (SST-) inte... ... hiện toàn bộ

GABA Neuron Alterations, Cortical Circuit Dysfunction and Cognitive Deficits in SchizophreniaSchizophrenia is a brain disorder associated with cognitive deficits that severely affect the patients' capacity for daily functioning. Whereas our understanding of its pathophysiology is limited, postmortem studies suggest that schizophrenia is associated with deficits of GABA-mediated synaptic transmission. A major role of GABA-mediated transmission may be producing synchronized network ... ... hiện toàn bộ

The Role and Mechanisms of Action of Glucocorticoid Involvement in Memory StorageAdrenal steroid hormones modulate learning and memory processes by interacting with specific glucocorticoid receptors at different
brain areas. In this article, certain components of the physiological response to stress elicited by learning situations are proposed to form an
integral aspect of the neurobiological mechanism underlying memory formation. By reviewing the work carried out in d... ... hiện toàn bộ
