Co-activators and Co-repressors02:04

Co-activators and Co-repressors

8.7K
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

tRNA Activation02:26

tRNA Activation

23.0K
Aminoacyl-tRNA synthetases are present in both eukaryotes and bacteria. Though eukaryotes have 20 different aminoacyl-tRNA synthetases to couple to 20 amino acids, many bacteria do not have genes for all of these aminoacyl-tRNA synthetases. Despite this, they still use all 20 amino acids to synthesize their proteins. For instance, some bacteria do not have the gene encoding the enzyme that couples glutamine with its partner tRNA. In these organisms, one enzyme adds glutamic acid to all of the...

Activation Energy01:26

Activation Energy

86.9K
Activation energy is the minimum amount of energy necessary for a chemical reaction to move forward. The higher the activation energy, the slower the rate of the reaction. However, adding heat to the reaction will increase the rate, since it causes molecules to move faster and increase the likelihood that molecules will collide. The collision and breaking of bonds represents the uphill phase of a reaction and generates the transition state. The transition state is an unstable high-energy state...

Eukaryotic Transcription Activators

12.9K
Transcription activators are proteins that promote the transcription of genes from DNA to RNA. In most cases, these proteins contain two separate domains ‒ a domain that binds to DNA and a domain for activating transcription; however, in some cases, a single domain is responsible for both binding and activation of transcription, as seen in the glucocorticoid receptor and MyoD.
The binding domains are capable of recognizing and interacting with regulatory sequences on the DNA. These...

Secondary Active Transport01:55

Secondary Active Transport

138.1K
One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

Primary Active Transport01:47

Primary Active Transport

199.9K
In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...

Summary
This summary is machine-generated.

Hypnosis involves shifts in brain hemispheric dominance. Highly hypnotizable individuals show right-sided electrodermal activity shifts, while low hypnotizable individuals show left-sided shifts during hypnosis.

Area of Science:

  • Neuroscience
  • Psychology
  • Cognitive Science

Background:

  • Hemispheric dominance shifts have been theorized to influence hypnotic states.
  • Understanding brain lateralization is key to understanding consciousness and subjective experiences.

Purpose of the Study:

  • To investigate the role of hemispheric dominance shifts in hypnosis.
  • To correlate electrodermal activity laterality with hypnotizability and subjective hypnotic experience.

Main Methods:

  • Thirty-two participants underwent an active-alert hypnosis induction and a music-control condition.
  • Bilateral electrodermal activity was recorded to assess changes in hemispheric dominance.
  • Self-reported hypnosis experiences were collected.

Main Results:

  • Highly hypnotizable participants exhibited a shift towards right-sided electrodermal dominance during hypnosis.
  • Low hypnotizable participants showed a shift towards left-sided electrodermal dominance.
  • No significant laterality changes were observed in the control condition.
  • Subjective hypnosis experiences correlated with altered brain laterality.

Conclusions:

  • Hypnosis is associated with significant shifts in hemispheric dominance.
  • Right-hemispheric activity is crucial for the hypnotic state and subjective experience.
  • Individual differences in hypnotizability are reflected in distinct patterns of brain lateralization during hypnosis.
