Propagation of Action Potentials01:23

Propagation of Action Potentials

7.2K
The propagation of an action potential refers to the process by which a nerve impulse, or "action potential," travels along a neuron.
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium ions to...

Action Potential01:14

Action Potential

8.6K
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...

Higher Mental Functions of the Brain: Language

1.4K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Diencephalon: Thalamus and Information Relay01:27

Diencephalon: Thalamus and Information Relay

2.3K
The thalamus, often called “the gateway to the cerebral cortex,” is vital in processing and directing sensory and motor signals throughout the brain. Almost all inputs destined for the cerebral cortex, except for olfactory signals, are relayed through the thalamus. The thalamus is  a sophisticated relay station, channeling information from various brain regions to the cerebral cortex, as well as a filter, prioritizing certain signals over others based on current physiological...

Fixed Action Patterns01:06

Fixed Action Patterns

16.6K
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.

Area of Science:

  • Neuroscience
  • Cognitive Neuroscience
  • Neuroimaging

Background:

  • Shared neural substrates exist for action and language processing, notably in the left inferior frontal gyrus (IFG), premotor cortex (PMC), and inferior parietal lobule (IPL).
  • The precise nature of neural activity patterns and effective connectivity within these overlapping regions during semantically related action and language generation remains unclear.

Purpose of the Study:

  • To investigate whether activity patterns and information flow differ in shared brain regions during action versus verb generation tasks.
  • To explore the task-context dependency of neural processing in the PMC-IFG-IPL network.

Main Methods:

  • Functional magnetic resonance imaging (fMRI) was employed.
  • Participants performed hand action and verb generation tasks using object pictures.
  • Analysis included mean activation levels, multi-voxel pattern analysis (MVPA), and dynamic causal modeling (DCM).

Main Results:

  • Shared and distinct brain regions were identified for action and verb generation within the left PMC, IFG, and IPL.
  • MVPA revealed distinct activity patterns in shared sub-regions for the two tasks.
  • DCM indicated different information flow patterns across the PMC-IFG-IPL network for action and verb generation.

Conclusions:

  • Neuroimaging evidence suggests that action and verb generation are task-context driven within shared brain regions.
  • Distinct neural information flow patterns within the PMC-IFG-IPL network are modulated by polymodal processing in these shared areas.
