An Assay for Measuring the Effects of Ethanol on the Locomotion Speed of Caenorhabditis elegans

Ethanol affects the acquisition of information
Psychopharmacology
|January 1, 1980
Summary
Acute ethanol administration disrupted pigeons' performance in a memory task. However, this impairment could be overcome by adjusting stimulus exposure, suggesting ethanol affects information acquisition, not storage.
Area of Science:
- Neuroscience
- Behavioral Psychology
- Pharmacology
Background:
- Ethanol (ETOH) is known to affect cognitive functions.
- Understanding the specific mechanisms of ETOH's impact on memory is crucial.
Purpose of the Study:
- To investigate the effects of acute ethanol administration on memory in pigeons.
- To determine if ethanol disrupts information acquisition or storage.
Main Methods:
- Pigeons were administered varying oral doses of ethanol (0, 1.0, and 2.0 g/kg).
- Performance was assessed using a delayed pair comparison procedure.
- Stimulus exposure duration was manipulated to equate initial performance levels.
Main Results:
- Higher doses of ethanol (1.0 and 2.0 g/kg) significantly disrupted performance.
- Memory impairment was partially overcome by adjusting stimulus exposure duration.
- This suggests that the effects of ethanol are dose-dependent and related to initial learning.
Conclusions:
- Ethanol's disruptive effects on memory appear to be primarily related to the acquisition phase.
- The study provides evidence that ethanol does not significantly impair the subsequent storage of information.
- Findings support a hypothesis where ethanol impacts initial learning processes more than memory retention.

02:17Physical Properties of Ethers
Overview
An ether molecule has a net dipole moment due to the polarity of C–O bonds. Subsequently, boiling points of ethers are lower than those of alcohols of comparable molecular weight and slightly higher than those of hydrocarbons of comparable molecular weight (Table 1).
Ethers can act as hydrogen bond acceptors, making them more water-soluble than hydrocarbons, but since ethers cannot act as hydrogen bond donors, they are much less soluble in water than alcohols. Ethers are considered...

02:29Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
Overview
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.

02:36Acidity and Basicity of Alcohols and Phenols
Like water, alcohols are weak acids and bases. This is attributed to the polarization of the O–H bond making the hydrogen partially positive. Moreover, the electron pairs on the oxygen atom of alcohol make it both basic and nucleophilic. Protonation of an alcohol converts hydroxide, a poor leaving group, into water—a good one. The two acid–base equilibria corresponding to ethanol are depicted below.
01:19Aldehydes and Ketones with Alcohols: Hemiacetal Formation
Similar to water, alcohols can add to the carbonyl carbon of the aldehydes and ketones. The addition of one molecule of alcohol to the carbonyl compound forms the hemiacetal or half acetal. As depicted below, in a hemiacetal, the carbon is directly linked to an OH and OR group.
01:27CNS Depressants: Alcohol and Nicotine
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...
01:27Production of Alcohol
Continuous fermentation is a key strategy in industrial ethanol production, particularly when efficiency, scalability, and high yields are essential. This approach allows for uninterrupted operation and optimized resource utilization. The primary feedstock, corn starch, undergoes enzymatic hydrolysis facilitated by α-amylase and glucoamylase. These enzymes break down the starch into fermentable sugars such as glucose, which are readily assimilated by fermentative microorganisms.Fermentation...
