Fixed Action Patterns

Fixed Action Patterns

A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Action Potential

Neurons communicate by firing action potentials—the electrochemical signal that is propagated along the axon. The signal results in the release of neurotransmitters at axon terminals, thereby transmitting information to the nervous system. An action potential is a specific "all-or-none" change in membrane potential that results in a rapid spike in voltage.
Membrane potential in neurons
Neurons typically have a resting membrane potential of about -70 millivolts (mV). When they receive...

Personal Identity

Personal Identity

Personal identity is the deeply felt sense of self that individuals cultivate over time, intricately woven from intrinsic qualities they consider essential to their existence—qualities such as morality, intelligence, and friendliness. These attributes serve as vital internal benchmarks, guiding individuals in evaluating whether their actions resonate with their true selves.When personal identity takes center stage in one's life, individuals often emphasize their distinctiveness,...

Antibody Actions

Antibody Actions

Antibodies, or immunoglobulins, are critical players in the immune system's arsenal against invading pathogens. Produced by B cells and plasma cells, their primary role is to detect and bind to specific antigens, molecules found on the surface of pathogens like bacteria or viruses. Beyond antigen recognition, antibodies perform several vital functions that contribute to immune defense.
Neutralization
Antibodies can bind to pathogens, preventing them from infecting host cells. This process...

Summary

Playing first-person shooter (FPS) video games enhances cognitive skills and induces lasting brain structure changes, particularly in the thalamus, even months after gameplay. This study demonstrates long-term benefits of gaming on attention and perception.

Area of Science:

Neuroscience
Cognitive Psychology
Neuroimaging

Background:

Cross-sectional studies suggest video gaming alters cognitive skills and brain structure.
The persistence of these changes post-training remains largely unknown.

Purpose of the Study:

To quantify the immediate and long-lasting cognitive and morphometric effects of systematic first-person shooter (FPS) video game exposure.
To investigate if observed brain changes persist beyond the gaming period.

Main Methods:

Thirty-five healthy participants were divided into a gaming and control group.
Cognitive assessments and structural magnetic resonance imaging (MRI) were conducted at baseline, immediately post-gaming, and after 3 months.
Voxel-wise regression analysis was used to link baseline pulvinar volume with gaming performance changes.

Main Results:

Cognitive performance improved in perceptual and attentional measures immediately and 3 months post-gaming.
Immediate structural brain changes were observed in the thalamus, superior temporal gyrus, precentral gyrus, and middle occipital gyrus.
Significant pulvinar volume changes persisted at 3 months, correlating with gaming performance.

Conclusions:

Systematic video game play, specifically FPS games, can induce beneficial, long-lasting cognitive and structural brain changes.
The persistence of thalamic changes suggests a link between FPS gaming and thalamo-cortical networks involved in attention and sensory integration.
