Frontiers in Psychiatry, 2013 Background: The understanding of physiopathology and cognitive impairments in mood disorders requires finding objective markers. Mood disorders have often been linked to hypometabolism in the prefrontal dorsolateral cortex, and to GABAergic and ...

Variability in non-invasive brain stimulation studies: reasons and results [PDF]
, 2018 Non-invasive brain stimulation techniques (NIBS), such as Theta Burst Stimulation (TBS), Paired Associative Stimulation (PAS) and transcranial Direct Current Stimulation (tDCS), are widely used to probe plasticity in the human motor cortex (M1). Although

Many specialists for suppressing cortical excitation [PDF]
frontiers in Neuroscience, 2008 Cortical computations are critically dependent on GABA-releasing neurons for dynamically balancing excitation with inhibition that is proportional to the overall level of activity. Although it is widely accepted that there are multiple types of interneurons, defining their identities based on qualitative descriptions of morphological, molecular and ...

PTEN: A master regulator of neuronal structure, function, and plasticity. [PDF]
, 2014 PTEN (phosphatase and tensin homolog on chromosome ten) is a dual protein/lipid phosphatase that dephosphorylates PIP3, thereby inhibiting the AKT/mTOR pathway. This inhibition ultimately decreases protein translation, cell proliferation and cell growth.

Frontiers in Cell and Developmental BiologyThe cell cortex plays many critical roles, including interpreting and responding to internal and external signals. One behavior which supports a cell’s ability to respond to both internal and externally-derived signaling is cortical excitability, wherein

Transcranial Magnetic Stimulation as a Tool to Investigate Motor Cortex Excitability in Sport
Brain Sciences, 2021 Transcranial magnetic stimulation, since its introduction in 1985, has brought important innovations to the study of cortical excitability as it is a non-invasive method and, therefore, can be used both in healthy and sick subjects.

Logarithmic distributions prove that intrinsic learning is Hebbian
, 2017 In this paper, we present data for the lognormal distributions of spike rates, synaptic weights and intrinsic excitability (gain) for neurons in various brain areas, such as auditory or visual cortex, hippocampus, cerebellum, striatum, midbrain nuclei ...

Reach-To-Grasp Movements: A Multimodal Techniques Study [PDF]
, 2018 The aim of the present study was to investigate the correlation between corticospinal activity, kinematics, and electromyography (EMG) associated with the execution of precision and whole-hand grasps (WHGs).

Neural Avalanches at the Critical Point between Replay and Non-Replay of Spatiotemporal Patterns [PDF]
, 2013 We model spontaneous cortical activity with a network of coupled spiking units, in which multiple spatio-temporal patterns are stored as dynamical attractors.
