The collective and coordinated synaptic activity of large neuronal populations is relevant to neuronal development as well as a range of neurological diseases. Quantification of synaptically-mediated neuronal signalling permits further downstream analysis as well as potential application in target validation and in vitro screening assays. Our aim is to develop a phenotypic quantification for neuronal activity imaging data of large populations of neurons, in particular relating to the spatial component of the activity.

Synaptic plasticity consists in a change in structure and composition of presynaptic and postsynaptic compartments. For a long time, synaptic plasticity had been thought as a neuronal mechanism only u...
The signaling scaffold protein GIT1 is expressed widely throughout the brain, but its function in vivo remains elusive. Mice lacking GIT1 have been proposed as a model for attention deficit-hyperactiv...
Harvesting in space affects, in general, the spatial scale of the synchrony in the population fluctuations, which determines the size of the areas subjected to simultaneous quasi-extinction risk. Here...
The role of mossy cells (MCs) of the hippocampal dentate area has long remained mysterious. Recent research has begun to unveil their significance in spatial computation of the hippocampus. Here, we u...
Steroids have been demonstrated to play profound roles in the regulation of hippocampal function by acting on their receptors, which need coactivators for their transcriptional activities. Previous st...
The main objective of the study is to define, for Autism Spectrum Disorder, the extent of genetic variation in synaptic pathways that may be targeted for therapeutic development. For this ...
The project is targeting cognitive impairment, one of the main health problems of patients with RAS pathway disorders. The aim of this study is to translate findings of animal studies to h...
This study aims to measure synaptic density in the brains (including in ventral striatum [VS] and medial prefrontal cortex [mPFC]) of abstinent subjects with Cocaine Use Disorder (CUD) or ...
This study is designed to see if doing regular training on a spatial imagery task leads to improvements in the ability to do the trained spatial imagery task and in the ability to get arou...
Purpose of Study: A) To improve outcome in large population of antipsychotic patients with schizophrenia or schizoaffective who are only partial responders B) To increase understanding of...
Methods used to take into account and incorporate spatial autocorrelation and regional variation into regression analysis models of data that has spatial dependency, and also to provide information on the spatial relationships among the variables.
Physiological integration of multiple SYNAPTIC POTENTIAL signals to reach the threshold and initiate postsynaptic ACTION POTENTIALS. In spatial summation stimulations from additional synaptic junctions are recruited to generate s response. In temporal summation succeeding stimuli signals are summed up to reach the threshold. The postsynaptic potentials can be either excitatory or inhibitory (EPSP or IPSP).
A persistent activity-dependent decrease in synaptic efficacy between NEURONS. It typically occurs following repeated low-frequency afferent stimulation, but it can be induced by other methods. Long-term depression appears to play a role in MEMORY.
The communication from a NEURON to a target (neuron, muscle, or secretory cell) across a SYNAPSE. In chemical synaptic transmission, the presynaptic neuron releases a NEUROTRANSMITTER that diffuses across the synaptic cleft and binds to specific synaptic receptors, activating them. The activated receptors modulate specific ion channels and/or second-messenger systems in the postsynaptic cell. In electrical synaptic transmission, electrical signals are communicated as an ionic current flow across ELECTRICAL SYNAPSES.
Integration of spatial information perceived by visual and/or auditory CUES.
Immunoassay - ELISA
Immunoassays are quick and accurate tests to detect specific molecules. Immunoassays rely on an antibody to bind to the specific structure of a molecule. Antibodies are proteins generated by animals in response to the invasion of a foreign molecule (anti...
