Methods: We explored the role of learning in 2-bottle alcohol preference (AP) in mice by recording changes between days and periods (every 3 days the alcohol and water tubes were .
Anhedonia is the inability to experience pleasure from rewarding or enjoyable activities and is a core symptom of depression in humans. Here, we describe a protocol for the measurement of anhedonia in mice, in which anhedonia is measured by a sucrose preference test (SPT) based on a two-bottle choice paradigm.
2.1 Bottles and Scale. To perform a two-bottle sucrose preference test on rats and mice, we used customized glass bottles of volume 150 mL, or 50 mL Falcon tubes with scent-free chemical rubber tops and glass drinking spouts (length of 6 mm; the thickness of glass is 1.5 mm, internal diameter of the tip is app. 2.5–3 mm).Anhedonia is the inability to experience pleasure from rewarding or enjoyable activities and is a core symptom of depression in humans. Here, we describe a protocol for the measurement of anhedonia in mice, in which anhedonia is measured by a sucrose preference test (SPT) based on a two-bottle choice paradigm.Development of the protocol A two-bottle choice test measuring the preferred intake on nutrients (taste preference) has been applied in diet-intake studies for decades10. The ratio of a given . We run a three-phase validation protocol to ensure 1) proper choice of the sensor to detect licks; 2) adaptation of the device to a wireless transmission and realistic in silico tests; and 3) in .
used and reliable behavioural test to assess anhedonia in rodents, based on a two-bottle choice paradigm. To date, different protocols are in use, inducing variability between researchers and The 2-bottle preference test is a popular protocol for characterizing a rodent's selection of a variety of solutions. Little attention has been paid, however, to the role of learning in this . Two procedures were found to be the most commonly used for habituation to the sweet solution: an exposure to two bottles, one with sucrose and one with water (19 protocols, 109 studies, 26.3 %), for a period ranging from 1 h and up to 5 weeks; and a period of exposure to two bottles of sucrose, followed by another of exposure to a bottle of .An Open Source Automated Two-Bottle Choice Test Apparatus for Rats . Unfortunately, this protocol gives no information on the animal’s drinking microstructure. That is, all information .
1. Introduction. According to the World Health Organization, more than 280 million people of all ages suffer from depression. Less than half of them receive appropriate treatment for their disorder, and, in low- and middle-income countries, 75% of people receive no treatment at all [].The prevalence of depression varies from 0.4% to 15.7% in different countries of the world [].The sucrose preference test (SPT) is a widely used and reliable behavioural test to assess anhedonia in rodents, based on a two-bottle choice paradigm. To date, different protocols are in use, inducing variability between researchers and hampering comparisons between studies. Rodents are then tested for alcohol preference using the two-bottle choice test, where they can choose between ethanol or water solutions. . for an in-depth review of CPP protocols and studies).
Table 2 shows raw data obtained from the application of the two-bottle choice protocol before and after exposure to the alcohol vapor inhalation system . To determine the significance of these changes, we conducted a paired t-test analysis on both alcohol and water consumption (obtained using the steps presented in Statistical Analysis). Animals eat palatable foods and reject aversive foods, which makes measurement of taste perception possible using various behavioral techniques. Three different methods to accurately measure taste behavior are described here. First, two-bottle preference tests evaluate whether a taste compound (tastant) is preferred over water. A 2-bottle choice test protocol was used for assessing sucrose preference 61. Mice were single-housed for 24 h prior to testing and then throughout the experiment. .
The sucrose preference test (SPT) is a widely used and reliable behavioural test to assess anhedonia in rodents, based on a two-bottle choice paradigm. To date, different protocols are in use . The whole process contains four stages: (1) Preparation; (2) Habituation; (3) Training; (4) Test. In the preparation phase, test mice were subjected to a two-bottle choice paradigm to determine the levels of alcohol preference. Under this paradigm, mice can voluntarily take alcohol and develop a stable level of preference [1]. Novel mice were .

Sucrose preference test for measurement of stress
Two-bottle choice tests are widely used in animal experiments to determine preference between two liquids. The following design is a 3D printed, Arduino controlled two-bottle choice test that automatically reads and records drinking behaviour in rats to allow for detailed analysis of their drinking microstructure. While commercial products exist that use lickometers to measure the .
Anhedonia is described as a decreased ability to experience rewarding and enjoyable activities, a core symptom of major depressive disorder. The sucrose preference test (SPT) is a widely used and reliable behavioural test to assess anhedonia in rodents, based on a two-bottle choice paradigm. To date, different protocols are in use, inducing variability between researchers .2023 年8月5日，Bio-protocol . 两瓶选择试验(two-bottle-choice test)是一种评估动物饮用偏好的方法。在此实验中，动物面前会放置两个瓶子，一个装有待测溶液（如酒精），另一个通常装有水。 .
Sucrose preference test
D–G, Averaged over the two nights, during the first 2 h of testing, mice did not differ in number of quick switches between bottles (D, W = −7, p = 0.77) or in number of returns to either bottle following a pause from drinking (E, W = 35, p = 0.195) and during the last 2 h of testing mice did not differ in number of quick switches between .
Sucrose Preference Test to Measure Stress
The 20% ethanol intermittent-access (IAE) two-bottle-choice drinking procedure has been shown to produce high voluntary ethanol consumption in a number of rat strains. For this study, we applied this procedure to male Fischer (F344) rats, a strain previously reported to exhibit low levels of ethanol consumption. We also subjected these animals to a two-week . Animals eat palatable foods and reject aversive foods, which makes measurement of taste perception possible using various behavioral techniques. Three different methods to accurately measure taste behavior are described here. First, two-bottle preference tests evaluate whether a taste compound (tastant) is preferred over water.Intermittent access to 20% ethanol in a two-bottle-choice procedure (IA2BC) was used as a model of voluntary ethanol intake. Male Wistar rats (n = 24) had twenty 24-h sessions of free access to two-bottle choice (water or 20% ethanol) with 24-h withdrawal periods (water only). Control animals had access to water only (n = 11). Following pre-binge assessment of self-administration behavior, mice were given free-access to alcohol in a two-bottle choice procedure, based on the Drinking in the Dark paradigm [60, 61] but .
Intermittent Access to 20% Ethanol in a Two-Bottle-Choice Procedure. The IA2BC procedure was performed according to Simms and co-authors (Simms et al. 2008).Briefly, rats (n = 24) received twenty 24-h sessions of free access to two-bottle choice (water and 20% (v/v) ethanol) with 24-h withdrawal periods (water only).The placement of the ethanol bottle .
Measurement of Behavioral Taste Responses in Mice: Two
The rats were tested for ethanol intake and preference in a two-bottle (24 h long) choice test, shortly before (PD 30 or 70) and shortly after (PD 56 or 96) exposure to the binge or intraperitoneal protocol; and then tested for free-choice drinking during late adulthood (PDs 120–139) in intermittent two-bottle intake tests.
