psychedelics   auditory cortex   deviance detection   serotonin receptor   perceptual distortions  

The Impairment of Deviant Detection in the Auditory Cortex by the Serotonergic Psychedelic DOI Research Background Psychedelics are a class of psychoactive substances capable of significantly altering perception, cognition, and mood. They have recently regained attention due to their potential therapeutic value, such as in treating depression and a...

How Does Orientation-Tuned Normalization Spread Across the Visual Field?

Medicine, Neurology, Medical Imaging,
sensory processing   normalization   fMRI   surround suppression   contrast response functions  

Study on Orientation-Tuned Gain Control Mechanisms in the Visual Cortex Academic Background Visual perception is a complex neural process influenced by contextual environments. Surround suppression is an important phenomenon that describes how the perceived contrast of a stimulus is attenuated when surrounded by other stimuli. The neural mechanisms...

Not Fleeting but Lasting: Limited Influence of Aging on Implicit Adaptive Motor Learning and its Short-Term Retention

Medicine, Geriatrics, Neurology,
aging   implicit learning   motor adaptation   spontaneous recovery  

The Impact of Aging on Implicit Motor Learning and Short-term Memory: A Study Based on Force Field Adaptation Research Background Motor adaptation is the process by which the brain adjusts motor strategies in response to environmental changes, typically involving two mechanisms: explicit learning and implicit learning. Explicit learning is a rapid,...

Probing Sensorimotor Memory through the Human Speech-Audiomotor System

Medicine, Neurology,
sensorimotor memory   speech-auditory system   memory retention   contextual memory retrieval   speech motor learning  

Research Background Human sensorimotor learning and memory mechanisms have long been a research focus in the field of neuroscience. Most related studies have concentrated on the visuospatial workspace and limb movements, such as arm movements and grasping actions. These studies have helped scientists understand how sensorimotor memories are formed,...

Electroacupuncture Ameliorated Locomotor Symptoms in MPTP-Induced Mice Model of Parkinson’s Disease by Regulating Autophagy via Nrf2 Signaling
