Network plasticity in cortical assemblies
European Journal of Neuroscience, 2008AbstractTo investigate distributed synaptic plasticity at the cell assembly level, we used dissociated cortical networks from embryonic rats grown on grids of 60 extracellular substrate‐embedded electrodes (micro‐electrode arrays). We developed a set of experimental plasticity protocols based on the pairing of tetanic bursts (20 Hz) with low‐frequency ...

Synaptic plasticity in cortical systems
Current Opinion in Neurobiology, 1999Recent studies indicate that synapse addition and/or loss is associated with different types of learning. Other factors influencing synaptogenesis and synapse loss include neurotrophins, hormones, and the induction of long-term potentiation. An emerging view of synaptic plasticity suggests that local neurotrophin action and synaptically associated ...

Adenosine and Cortical Plasticity
The NeuroscientistBrain plasticity is the ability of the nervous system to change its structure and functioning in response to experiences. These changes occur mainly at synaptic connections, and this plasticity is named synaptic plasticity. During postnatal development, environmental influences trigger changes in synaptic plasticity that will play a crucial role in the

Plasticity in auditory cortical circuitry
Current Opinion in Neurobiology, 1994Recent studies have focused on the mechanisms and conditions yielding the short- and long-term plasticity exhibited by neuronal responses in the primary auditory cortex of adults. These investigations have examined factors operating at the cellular and intercellular levels, the effects of global behavioral states and the role of the cholinergic system,

Annals of the New York Academy of Sciences, 2001
Abstract: Auditory experience changes the make‐up of areas in the cerebral cortex that are involved in the processing of complex sounds, including music. Evidence for this comes from various lines of research. Early blindness results in an expansion of auditory‐responsive areas in the parietal cortex and a refinement in the selectivity of neurons in ...

Hippocampal contributions to cortical plasticity
Neuropharmacology, 1998The hippocampal complex and neocortex are both integrally important in memory function, in particular as regards memory for episodes and knowledge about the world that is derived from them. It is traditionally assumed that the role of the hippocampus is time-limited, after which retrieval of episodic memory depends only upon neocortical stores.

Architectural Design, 2009
AbstractCould the near future for architects all be in the mind? With further neurological metamorphosis, Dan Farmer suggests that spatial awareness and experience could be stipulated by cortical plasticity, stimulated by electrical impulses. With this shift to internalised space perception, the disciplines of architecture and cognitive science become ...

Local cortical interactions determine the form of cortical plasticity
Journal of Neurobiology, 1999Competitive interactions between left and right eye inputs to visual cortex during development are usually explained by the thalamocortical axons competing more or less well for cortical territory during retraction into eye specific domains. Here we review the evidence for competitive and co-operative interactions between cortical columns in barrel ...

Laminar Comparison of Somatosensory Cortical Plasticity
Science, 1994During tactile learning there is a transformation in the way the primary somatosensory cortex integrates, represents, and distributes information from the skin. To define this transformation, the site of earliest modification has been identified in rat somatosensory cortex after a change in sensory experience.
