Covalently Linked Protein Regulators02:04

Covalently Linked Protein Regulators

9.6K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....

X-linked Traits01:19

X-linked Traits

58.8K
In most mammalian species, females have two X sex chromosomes and males have an X and Y. As a result, mutations on the X chromosome in females may be masked by the presence of a normal allele on the second X. In contrast, a mutation on the X chromosome in males more often causes observable biological defects, as there is no normal X to compensate. Trait variations arising from mutations on the X chromosome are called “X-linked”.

What is Behavior?00:54

What is Behavior?

10.3K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

Enzyme-linked Receptors01:00

Enzyme-linked Receptors

86.7K
Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

Sex-linked Disorders01:43

Sex-linked Disorders

109.1K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Area of Science:

  • Visual Neuroscience
  • Computational Neuroscience
  • Primate Vision Research

Background:

  • Understanding the precise relationship between neural activity and behavior is a key challenge in visual neuroscience.
  • Early visual cortex (V1) plays a critical role in processing visual information.

Purpose of the Study:

  • To review efforts in developing and testing quantitative models that link neural responses in V1 to primate behavior.
  • To introduce and discuss the decoder linking model (DLM) framework.
  • To explore the properties of primate V1 relevant to modeling neural-behavior relationships.

Main Methods:

  • Measuring and perturbing neural activity in primary visual cortex (V1) of nonhuman primates.
  • Utilizing demanding and well-controlled visual tasks for behavioral assessment.
  • Applying the decoder linking model (DLM) framework to analyze neural data and predict behavior.

Main Results:

  • The DLM framework provides a conceptual approach to link neural responses to behavioral output.
  • Current literature is reviewed from the perspective of the DLM framework.
  • Key properties of primate V1 relevant to this modeling approach are discussed.

Conclusions:

  • The DLM framework offers a systematic way to investigate the neural basis of visual perception and behavior.
  • Technological and theoretical advancements are expected to accelerate progress in understanding V1's role in behavior.
  • Further research is needed to refine models and fully elucidate the V1 activity-behavior link.
