Corollary Discharge: How Your Brain Predicts Reality Corollary discharge, often referred to as reafference, serves as a critical neural process that allows the brain to distinguish between self-gener

COROLLARY DISCHARGE Introduction to Corollary Discharge Corollary discharge, also known as reafference or reafferent discharge, is a fundamental neural mechanism in which the brain’s motor control system actively sends a predictive signal to its sensory systems. This anticipatory signal is dispatched either before or concurrently with a self-initiated movement, essentially informing the sensory apparatus about […]

NMDA HYPOTHESIS OF CONSCIOUSNESS

NMDA Hypothesis of Consciousness: A Review Consciousness is a complex phenomenon that has been studied for centuries, yet its neural mechanisms remain largely unknown. One hypothesis that seeks to explain the emergence of consciousness is the NMDA Hypothesis of Consciousness. This hypothesis proposes that the glutamate-gated N-methyl-d-aspartate (NMDA) receptor is a key component in the […]

SACCADIC TIME

Foundations of Saccadic Time and Visual Perception The human visual system is a remarkably sophisticated apparatus that allows for the seamless perception of a stable world despite the constant, rapid movements of the eyes. Central to this stability is the concept of saccadic time, a neuropsychological phenomenon wherein the brain effectively compresses the temporal sequence […]

CONTRALATERAL CONTROL

Abstract The concept of contralateral control is fundamental to understanding how the central nervous system manages and executes motor actions. This hypothesis posits a dual system wherein motor behavior is primarily mediated by the contralateral control system, responsible for the initiation, planning, and precise execution of movement, and supplemented by the ipsilateral control system, which […]

FEELING OF KNOWING

Defining the Feeling of Knowing (FOK) The Feeling of Knowing (FOK) is a fascinating and ubiquitous phenomenon within cognitive psychology, characterized by an introspective experience where an individual is certain they possess specific knowledge or an answer, yet are temporarily unable to access or retrieve the detailed information (Tulving, 1985). This state represents a crucial […]

TEMPORAL SUMMATION

Introduction and Definition of Temporal Summation Temporal summation represents a critical neural mechanism fundamental to the integrative capacity of the nervous system, describing the process by which a neuron combines the effects of multiple, subthreshold synaptic inputs arriving sequentially at the same synapse over a short period of time. This sophisticated integration is essential for […]

MENTAL MECHANICS

MENTAL MECHANICS: Executive Functions in Psychology and Neuroscience The Core Definition of Executive Functions Executive functions (EFs) are a set of higher-level cognitive processes that serve as the brain’s management system, enabling goal-directed behavior, adaptive decision-making, and self-regulation. Simply put, they are the mental tools that allow us to resist immediate impulses, plan for the […]

REFLEX INHIBITION

Reflex Inhibition Introduction: The Core Definition of Reflex Inhibition Reflex inhibition is a fundamental neurophysiological phenomenon characterized by the suppression or attenuation of an involuntary reflex response to a given stimulus. At its core, it represents the nervous system’s capacity to modulate its own automatic reactions, ensuring adaptive and context-appropriate behavior. This intricate process allows […]

TIME ERROR

TIME ERROR The Core Definition of Time Error A fundamental aspect of human experience involves our ability to perceive and interact with the dimension of time; however, this perception is not always perfectly aligned with objective reality. The concept of time error, a central construct in cognitive neuroscience, precisely quantifies this discrepancy, referring to the […]
