The EU will first address the main communication pathways between normal cells and intracellular signal transduction pathways encountered in physiological and neurophysiological mechanisms. Thus, G protein-coupled receptors (GPCRs) will be studied, specifically their structure, function, and modulation by interacting proteins involved, in particular, in the phenomenon of desensitization. The main intracellular pathways activated by membrane-bound GPCRs will be discussed (MAP kinase pathways, PI3 kinase, etc.).

Next, a significant portion of the course will focus on calcium signaling and Ca²⁺ homeostasis, as Ca²⁺ is a ubiquitous signal in cellular signaling. Calcium homeostasis will be studied in particular in the context of the lymphocyte response following antigenic stimulation. Furthermore, the production of oxygen free radicals—which cause oxidative stress—is dependent on intracellular Ca²⁺. The physiological role of free radicals will be discussed, as well as their involvement in oxidative stress. In this context, the protective mechanisms against oxidative stress will also be examined.The following chapter will address the endocannabinoid system, which serves to summarize all the topics previously covered in the course. The endocannabinoid system is responsible for numerous central and peripheral regulatory processes.

Finally, two other topics will be covered: the blood-brain barrier, which provides a framework for discussing cellular communication in a highly integrated manner between two environments, and the pancreatic β-cell, whose activity is crucial for regulating blood glucose levels through insulin secretion.

The overall objective of this course unit is to deepen students’ understanding of the concepts necessary for studying symbiotic interactions, whether parasitic or mutualistic. To this end, we will examine both the specific characteristics and the ubiquity of the parasitic lifestyle across the tree of life. We will discuss the defense mechanisms of host organisms, the concepts of favoring and manipulation, the consequences of host-symbiont interactions on life history traits, and the influence of these interactions on the diversification of organisms.

The lab sessions will provide an opportunity to explore these concepts in greater depth using examples of major interactions involving symbionts (viruses, bacteria, and unicellular and multicellular eukaryotes) and a variety of hosts (both unicellular and multicellular).

Behaviors—whether determined by conscious or unconscious processes—are based on complex neurobiological substrates. They are, in fact, underpinned by molecular and cellular changes within the nervous system that modulate the neural networks responsible for motor and emotional processes linked to an individual’s memory. These processes are fundamental in enabling the organism to develop an integrated behavioral response in close interaction with its environment, thereby ensuring the adaptation and survival of the individual and its species.

The topics covered in the Neurobiology of Behavior course will be as follows:

-Gene–Behavior

The Relationship Between Genotype and Phenotype—Environmental Impact—Attention Processes/Movement Planning—Behavioral Disorders (Genetic and Environmental Aspects)

-Memory and Synaptic Plasticity

Methodological approaches to studying synaptic plasticity: electrophysiology, optogenetics, animal models, behavioral tests—Factors regulating synaptic plasticity, including genetic and epigenetic factors—The relationship between plasticity and memory—The neurobiology of memory, forgetting, and reconsolidation
