Human Memory: Brain-State-Dependent Effects of Stimulation.

08:00 EDT 22nd May 2017 | BioPortfolio

Summary of "Human Memory: Brain-State-Dependent Effects of Stimulation."

A new study shows that direct stimulation of memory-relevant brain areas can enhance memory performance, but only when stimulation is applied during brain states associated with poor memory outcome - stimulation during optimal states results in a decrease in memory.

Stochastic resonance mediates the state-dependent effect of periodic stimulation on cortical alpha oscillations.

Brain stimulation can be used to engage and modulate rhythmic activity in brain networks. However, the outcomes of brain stimulation are shaped by behavioral states and endogenous fluctuations in brai...

A human prefrontal-subthalamic circuit for cognitive control.

The subthalamic nucleus is a key site controlling motor function in humans. Deep brain stimulation of the subthalamic nucleus can improve movements in patients with Parkinson's disease; however, for u...

Effects of Anodal Transcranial Direct Current Stimulation Over the Ventrolateral Prefrontal Cortex on Episodic Memory Formation and Retrieval.

In the past decade, several studies have investigated the effects of transcranial direct current stimulation (tDCS) on episodic memory abilities. However, the specific conditions under which tDCS affe...

Study on the Multi-level Resistance-Switching Memory and Memory-State-Dependent Photovoltage in Pt/Nd:SrTiO3 Junctions.

Pt/Nd:SrTiO3 (STO)/In devices were fabricated by depositing Schottky-contact Pt and Ohmic-contact In electrodes on a single crystal STO with Nd doping. The Pt/Nd:STO/In devices show multi-level resist...

Dose dependent effects of intranasal insulin on resting-state brain activity.

Insulin action in the human brain influences eating behavior, cognition, and whole-body metabolism. Studies investigating brain insulin rely on intranasal application.

Deep Brain Stimulation (DBS) for Alzheimer's Disease

Background: Alzheimer disease (AD) is a debilitating brain disorder that affects over 4.75 million people in the US and Canada. People with AD have difficulty remembering general facts and...

Effects of Brain Stimulation During a Daytime Nap on Memory Consolidation in Older Adults

The beneficial effect of nocturnal as well as daytime sleep on memory consolidation is well-documented in young, healthy subjects. Slow wave sleep (SWS), in particular, with its slow oscil...

Effects of Brain Stimulation During Nocturnal Sleep on Memory Consolidation in Younger, Healthy Subjects

The beneficial effect of nocturnal sleep on memory consolidation is well-documented in young, healthy subjects. Especially, periods rich in slow-wave sleep (SWS) have shown a memory enhanc...

Effects of rTMS on Human Brain Activity Measured With EEG and fMRI

This project investigates the effects of repetitive transcranial magnetic stimulation (rTMS) on neural circuits as a function of spatiotemporal parameters and brain state in order to bette...

Medical and Biotech [MESH] Definitions

Stimulation of the brain, which is self-administered. The stimulation may result in negative or positive reinforcement.

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.

A state of prolonged irreversible cessation of all brain activity, including lower brain stem function with the complete absence of voluntary movements, responses to stimuli, brain stem reflexes, and spontaneous respirations. Reversible conditions which mimic this clinical state (e.g., sedative overdose, hypothermia, etc.) are excluded prior to making the determination of brain death. (From Adams et al., Principles of Neurology, 6th ed, pp348-9)

Adjustment of BRAIN WAVES from two or more neuronal groups within or across a brain structure (e.g., cortical and limbic brain structures) to become uniform in EEG oscillation patterns in response to a stimulus. It is interpreted as a brain integration sign during many processes such as learning, memory, and perception and involves reciprocal neural connections.

Type of declarative memory, consisting of personal memory in contrast to general knowledge.
