extensively reported in the literature. The effect of the interaction of those deprivation conditions
on food and water consumption and on the temporal organization and dynamics of behavior is less
known. In this study, we evaluated the effects of different conditions of food and water deprivation on the spatio-temporal dynamics of behavior when food and water are concurrently available. Six
rats were exposed to four different conditions: a) food deprivation, b) water deprivation, c) food
and water deprivation and d) no deprivation. Experimental sessions consisted of simultaneously
presenting a food pellet and a drop of water using a Concurrent Fixed Time 30 s schedule on two
dispensers located on opposite walls of an extended experimental chamber. Local (number of
drops of water and pellets consumed, head entries to dispensers) and translational (location,
displacement routes) patterns were recorded. We found differential effects of the deprivation
conditions on the aforementioned measures with no equivalent behavioral dynamics under food
and water deprivation. The results are discussed in terms of the modulating function of deprivation
conditions on measures of vigor and direction of behavior

Beyond Single Discrete Responses: An Integrative and Multidimensional Analysis of Behavioral Dynamics Assisted by Machine Learning
Frontiers in Behavioral Neuroscience

Nevertheless, under the standard approaches, the experimental analysis of behavior is based on the single response paradigm and the temporal distribution of discrete responses. Thus, the continuous analysis of spatial behavioral dynamics is a scarcely studied field. The technological advancements in computer vision have opened new methodological perspectives for the continuous sensing of spatial behavior. With the application of such advancements, recent studies suggest that there are multiple features embedded in the spatial dynamics of behavior, such as entropy, and that they are affected by programmed stimuli (e.g., schedules of reinforcement) at least as much as features related to discrete responses. Despite the progress, the characterization of behavioral systems is still segmented, and integrated data ana...

With the application of such advancements, recent studies suggest that there are multiple features embedded in the spatial dynamics of behavior, such as entropy, and that they are affected by programmed stimuli (e.g., schedules of reinforcement) at least as much as features related to discrete responses. Despite the progress, the characterization of behavioral systems is still segmented, and integrated data analysis and representations between discrete responses and continuous spatial behavior are exiguous in the experimental analysis of behavior. Machine learning advancements, such as t-distributed stochastic neighbor embedding and variable ranking, provide invaluable tools to crystallize an integrated approach for analyzing and representing multidimensional behavioral data. Under this rationale, the present work (1) proposes a multidisciplinary approach for the integrative and multilevel analysis of behavioral systems, (2) provides sensitive behavioral measures based on spatial dynamics and helpful data representations to study behavioral systems, and (3) reveals behavioral aspects usually ignored under the standard approaches in the experimental analysis of behavior. To exemplify and evaluate our approach, the spatial dynamics embedded in phenomena relevant to behavioral science, namely, water-seeking behavior and motivational operations, are examined, showing aspects of behavioral systems hidden until now.
