Summary
A newly recognized deep cortical layer, layer 6b (L6b), may be crucial for attention. The L6b attention theory (LAT) proposes this overlooked layer is key to understanding attention and cognition.
Area of Science:
- Neuroscience
- Cognitive Science
Background:
- Attention is vital for perception and cognition.
- Attention relies on feedback loops between cortical layer 5 and the thalamus.
- The precise circuits controlling these attention loops are not fully understood.
Purpose of the Study:
- To propose the L6b attention theory (LAT), a circuit-based model.
- To highlight the role of the deep cortical layer 6b (L6b) in attention.
- To extend existing theories of attention by incorporating L6b.
Main Methods:
- Circuit-based modeling.
- Review of recent advances in neuroscience.
- Theoretical framework development.
Main Results:
- Layer 6b (L6b) neurons are positioned to control feedback loops.
- L6b neurons integrate top-down cortical input and neuromodulation.
- L6b projections are uniquely suited to regulate attention circuits.
Conclusions:
- The L6b attention theory (LAT) posits layer 6b as a critical, overlooked component of attention.
- LAT offers new insights into the neural basis of attention and cognition.
- Understanding L6b's role may illuminate neuropsychiatric disorders and self-awareness.

01:15Theories of Dissolution: Diffusion Layer Model
1.7K
Dissolution, the process by which drug particles dissolve in a solvent, is explained by the diffusion layer model, a theoretical framework that simulates the absorption of oral drugs and allows us to analyze experimental data.
This process starts with a thin layer, saturated with the drug, forming at the interface between the solid and liquid. The solute then diffuses from this layer into the main solution. The Noyes-Whitney equation suggests that the rate of dissolution relies on the diffusion...

17.1K
When two or more atoms come together to form a molecule, their atomic orbitals combine and molecular orbitals of distinct energies result. In a solid, there are a large number of atoms, and therefore a large number of atomic orbitals that may be combined into molecular orbitals. These groups of molecular orbitals are so closely placed together to form continuous regions of energies, known as the bands.
The energy difference between these bands is known as the band gap.

Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).

02:59The Atomic Theory of Matter
127.2K
The earliest recorded discussion of the basic structure of matter comes from ancient Greek philosophers. Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, meaning “indivisible.” Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements” — fire, earth, air, and water — and could be infinitely divided. Interestingly, these philosophers...

Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.
