INTRACRANIAL SELF-STIMULATION

Introduction and Definition of Intracranial Self-Stimulation Intracranial self-stimulation (ICSS) is a fundamental experimental technique employed extensively in behavioral neuroscience and psychopharmacology to investigate the neural substrates underlying reward, motivation, and reinforcement. The core principle of ICSS is the observation that animals, typically rodents, will voluntarily initiate and sustain electrical stimulation delivered directly to specific regions […]

LASHLEY, KARL

Introduction and Early Life of Karl Lashley Karl Spencer Lashley, born in 1890, stands as one of the most profoundly influential figures in the history of physiological psychology and neuroscience, dedicating his career to the monumental task of locating the physical basis of memory—a hypothetical construct he termed the engram. His work fundamentally challenged the […]

LOCOMOTOR ARREST

Introduction to Locomotor Arrest Locomotor arrest, in the context of neurophysiology and behavioral psychology, describes the abrupt and often complete cessation of voluntary movement induced by specific neural manipulations or potent environmental stimuli. It represents a critical inhibitory phenomenon distinct from simple fatigue or paralysis, characterized fundamentally by the active suppression of motor output pathways. […]

PATTERN CODING

Introduction and Definition of Pattern Coding Pattern coding fundamentally addresses the method by which information is represented and transmitted within the nervous system, particularly concerning sensory input. It moves beyond simpler models of information transfer, positing that the meaning of a neural signal is encoded not merely by the average frequency of action potentials—known as […]

PREMOTOR THEORY OF ATTENTION

Premotor Theory of Attention The Core Definition of the Premotor Theory The Premotor Theory of Attention (PTA) posits a profound and fundamental connection between the cognitive process of selecting information—what we call attention—and the systems responsible for preparing and executing physical movements. In its simplest form, the theory argues that shifting spatial attention is not […]

BEHAVIORAL NEUROSCIENCE

Behavioral Neuroscience The Core Definition and Scope of Behavioral Neuroscience Behavioral Neuroscience, often referred to synonymously with biological psychology, biopsychology, or physiological psychology, stands as a fundamental interdisciplinary field dedicated to understanding the neural basis of behavior. At its core, it seeks to explain how the structures and functions of the nervous system, particularly the […]

BIOLOGICAL PSYCHOLOGY

Biological Psychology: Investigating the Neural Basis of Behavior Defining Biological Psychology Biological psychology, frequently referred to as biopsychology or physiological psychology, stands as the scientific study of the biological underpinnings of behavior and mental processes. At its core, this field seeks to establish the causal relationship between physiological events and psychological phenomena, operating on the […]

SHUTTLE BOX

SHUTTLE BOX The Shuttle Box: A Definitive Overview The shuttle box is a venerable and widely utilized laboratory apparatus in experimental psychology and behavioral neuroscience, primarily employed to investigate avoidance learning and assess levels of anxiety and fear in animal models, typically rodents. At its core, it is a dual-compartment chamber designed to compel an […]

COORDINATION

Coordination in Psychology and Neuroscience The Core Definition of Coordination Coordination in the context of psychology and neuroscience refers to the intricate process by which multiple, often disparate, elements of behavior are integrated and harmonized to produce a unified, coherent, and goal-directed response. This fundamental concept underpins nearly all complex human activities, from simple motor […]

BEHAVIORAL APPROACH SYSTEM (BAS)

BEHAVIORAL APPROACH SYSTEM (BAS) Introduction to the Behavioral Approach System The Behavioral Approach System (BAS) is a fundamental neurobiological system that governs an individual’s motivation to pursue rewards and engage in goal-directed behaviors. At its core, the BAS is responsible for detecting signals associated with potential rewards and activating an appetitive, or approach, response. This […]
