Research in the Laboratory for Integrative Neuroscience (LIN) examines the role of particular molecules in control of actions, acute alcohol intoxication, alcohol seeking behavior, alcohol use disorder and habitual behavior. Another aim of research in LIN is to examine the molecular mechanisms of synaptic modulation and plasticity related to action and habit learning. An important unifying theme of research within LIN is investigation of forebrain mechanisms involved in aspects of cognition and behavioral control that contribute to addiction. We seek to understand the neural basis of addiction-related brain functions such as decision-making, goal-directed behavior, habit formation and habitual behavior. We are also examining mechanisms underlying specific responses to addictive drugs, including acute intoxication and neural adaptations to chronic drug exposure, such as tolerance and dependence. Gaining an understanding of these functions will necessarily involve determining which neural circuits mediate these processes, what physiological and synaptic mechanisms underlie circuit function and plasticity, and what neural and synaptic molecules play key parts in synaptic, neuronal and circuit function. We believe that these goals can best be achieved by bringing together investigators with a shared interest in these subjects and with diverse technological expertise so that we can approach the problem at multiple levels of analysis.

We envision that the shared interests of investigators from LIN and other NAAA laboratories and the interactive nature of these laboratories, will allow different investigators to combine their expertise in the analysis of neural function at multiple levels. For example, changes in addiction-related behavior in a particular mouse model can be examined in conjunction with analysis of neuronal morphology, signaling in subcellular compartments, and neural circuit function at the micro and macro levels. Examination of molecular expression, location and function can also be applied in the same animals. Ultimately, this should allow us to gain a thorough understanding of the way in which particular neuronal molecules contribute to cellular and circuit functions that ultimately influence behavior. We also envision that interactions and collaborations with other NIAAA and NIH laboratories will enhance our ability to analyze these neural functions from the molecule to the whole mouse.

One theme that brings together the different lines of research within LIN is an interest in mechanisms of addiction and habitual behavior. We predict that gaining a better understanding of synaptic plasticity in cortical-basal ganglia networks will help us to better appreciate how information relevant to habit formation becomes encoded. Our overarching hypothesis is that effects of addictive substances on synaptic structure and transmission will interface with natural plasticity mechanisms to focus habits on drugs of abuse as well as associated stimuli and responses. Thus, understanding the neural basis of habit formation and the molecular actions of intoxicating/addictive substances will allow us to gain a more thorough understanding of addiction. Ultimately, it is hoped that these lines of research can contribute to development of better therapies for neurological disorders and alcoholism.
