Prediction of HIV-1 Coreceptor Usage (Tropism) by Sequence Analysis using a Genotypic Approach

Prediction of HIV-1 Coreceptor Usage (Tropism) by Sequence Analysis using a Genotypic Approach

The prediction of the coreceptor usage of HIV-1 is required for the administration of a new class of antiretroviral drugs, i.e. coreceptor antagonists. It can be performed by sequence analysis of the env gene and subsequent interpretation through an internet based interpretation system...

An Introduction to Reward and Addiction

An Introduction to Reward and Addiction

Consequences play a major role in controlling our behavior. If the consequence is a reward, then it encourages the associated behavior. Rewards can come in many forms such as a pleasant feeling, money, or food. However, sometimes an individual engages in compulsive behavior despite of negative consequences, and this state is known as addiction. Administration of addictive substances is neurochemically rewarding, which ultimately causes a loss of control in limiting the intake. Scientists aim...

Methods to Discover Alternative Promoter Usage and Transcriptional Regulation of Murine Bcrp1

Methods to Discover Alternative Promoter Usage and Transcriptional Regulation of Murine Bcrp1

With the murine ABC transporter Bcrp1 (Abcg2) as an example, in-silico protocols are presented to detect alternative promoter usage in genes expressed in mouse tissues, and to evaluate the functionality of the alternative promoters identified using reporter...

Methods to Explore the Influence of Top-down Visual Processes on Motor Behavior

Methods to Explore the Influence of Top-down Visual Processes on Motor Behavior

It is unclear how top-down signals from the ventral visual stream affect movement. We developed a paradigm to test motor behavior towards a target on a 3D depth inversion illusion. Significant differences are reported in both deliberate, goal-directed movements and automatic actions under illusory and veridical viewing...

Perspectives on Sensation and Perception

Perspectives on Sensation and Perception

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University
The study of sensation—how signals are transduced from sensory organs, like the eyes—and perception—how the brain interprets these messages—has a rich history dating back to the 19th century, when great strides were made in understanding the properties of light and how they relate to the visual system. Importantly, such sensory and perceptual processes determine what we see, feel, taste, and hear in...

Holistic Facial Composite Creation and Subsequent Video Line-up Eyewitness Identification Paradigm

This applied experimental paradigm replicates circumstances by which an eyewitness to a real crime may create a holistic facial composite of the culprit from memory, and then attempt to identify the culprit from a video line-up containing the culprit or one in which he or she is not...

Summary

This summary is machine-generated.

Higher alcohol consumption enhances holistic perception for alcohol cues but impairs it for non-alcohol cues. This suggests alcohol use alters visual processing, potentially impacting addiction and recovery.

Background:

Holistic perception is an automatic, experience-dependent visual processing mechanism prioritizing salient stimuli.
Previous research suggests that substance use can influence attentional processes and perception.

Purpose of the Study:

To investigate the relationship between alcohol consumption levels and holistic perception of alcohol-related cues.
To explore whether alcohol consumption affects holistic perception of non-alcohol cues.
To examine the context-dependency of these perceptual alterations.

Main Methods:

Three experiments were conducted involving participants with varying levels of regular alcohol consumption.
Participants completed tasks assessing holistic perception of alcohol and non-alcohol cues under different conditions.
Statistical analyses were used to correlate alcohol usage with holistic perception measures.

Main Results:

Increased regular alcohol consumption was associated with enhanced holistic perception of alcohol cues.
This enhancement was specific to alcohol cues and not observed for non-alcohol cues.
Higher alcohol consumption predicted decreased holistic perception for non-rewarding cues when alcohol images were absent, indicating context-dependent effects.

Conclusions:

Alcohol consumption is linked to inverse alterations in holistic perception for alcohol versus non-alcohol cues.
These findings suggest a potential reutilization of cortical resources for alcohol cues at the expense of other stimuli.
Further research is needed to understand holistic perception's role in addiction maintenance, abstinence, and related traits.
