Why do some babies react to perceived danger more than others? According to new research from Michigan State University and the University of North Carolina, Chapel Hill, part of the answer may be found in a surprising place: an infant's digestive system.
God designed us in such a way that in times of intense difficulty, we have a built-in moment to turn to Him for help.
Study highlights the importance of sensory connections in fear learning Has your heart ever started to race at the thought of an upcoming deadline for work? Or has the sight of an unknown object in a dark room made you jump? Well, you can probably thank your amygdala for that. The small almond-shaped brain structure is central to how we perceive and process fear. As we start to learn to associate fear with cues in our environment, neuronal connections within the amygdala are dynamically altered in a process called synaptic plasticity. Although this physiological mechanism is important for fac...
Severe stress is among the most robust risk factors for the development of psychiatric disorders. Imaging studies indicate that life stress is integral to shaping the human brain, especially regions involved in processing the stress response. Although this is likely underpinned by changes to the cytoarchitecture of cellular networks in the brain, we are yet to clearly understand how these define a role for stress in human psychopathology. In this review, we consolidate evidence of macro-structural morphometric changes and the cellular mechanisms that likely underlie them. Focusing on stress-se...
Study: Graphene nanoparticles interfere with the development of anxiety-related behaviors in vertebrates New research shows that the nanomaterial acts on the excitatory synapses, interfering with the development of anxiety related behaviors in vertebrates. Effective, specific, with a reversible and non-harmful action: the identikit of the perfect biomaterial seems to correspond to graphene flakes, the subject of a new study carried out by SISSA - International School for Advanced Studies of Trieste, Catalan Institute of Nanoscience and Nanotechnology (ICN2) of Barcelona and the National Graph...
