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...

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...

Principles of Drug Action

Principles of Drug Action

Drugs are chemical substances that modify biological responses by interacting with macromolecular targets such as receptors, ion channels, transporters, and enzymes. Pharmacodynamics describes the course of action of drugs leading to the physiological effect at a specific site in the body.
Drugs can be agonists or antagonists. Like the endogenous ligands, agonists always bind and activate the target to produce a cellular response. Agonist binding induces a conformational change which in turn...

Neuroscience

Background:

Striatal neurons are hypothesized to encode action-values guiding economic decisions.
Previous studies relied on correlating neural activity with reward-seeking behavior during learning.

Purpose of the Study:

To critically re-evaluate the evidence for striatal action-value representation.
To identify and address methodological confounds in prior research.
To propose and test alternative analytical approaches.

Main Methods:

Analysis of temporal correlations in neuronal data.
Examination of experimental designs for dissociating decision variables.
Application of a novel analytical solution to existing datasets.

Main Results:

Weak temporal correlations can lead to false positives in identifying action-value representations.
Existing methods fail to adequately separate action-value signals from other neural correlates of decision-making.
Re-analysis of previously identified 'action-value' neurons in the basal ganglia revealed no significant action-value representation.

Conclusions:

The prevailing hypothesis of striatal action-value encoding requires re-examination.
Methodological improvements are necessary to accurately identify neural representations of value in decision-making.
Further research with refined experimental and analytical techniques is needed to confirm or refute the role of striatal neurons in encoding action-values.
