Intranasal Insulin for Alzheimer's Disease.
Brain insulin signaling contributes to memory function and might be a viable target in the prevention and treatment of memory impairments including Alzheimer's disease. This short narrative review explores the potential of central nervous system (CNS) insulin administration via the intranasal pathway to improve memory performance in health and disease, with a focus on the most recent results. Proo…

Memory-Related Synaptic Plasticity Is Sexually Dimorphic in Rodent Hippocampus.
Men are generally superior to women in remembering spatial relationships, whereas the reverse holds for semantic information, but the neurobiological bases for these differences are not understood. Here we describe striking sexual dimorphism in synaptic mechanisms of memory encoding in hippocampal field CA1, a region critical for spatial learning. Studies of acute hippocampal slices from adult rat…

Subcortical Local Functional Hyperconnectivity in Cannabis Dependence.
Cannabis abuse (CA) has been associated with psychopathology, including negative emotionality and higher risk of psychosis, particularly with early age of initiation. However, the mechanisms underlying this association are poorly understood. Because aberrant dopamine signaling is implicated in cannabis-associated psychopathology, we hypothesized that regular CA would be associated with altered res…

Memory in health and in schizophrenia.
Memory is an important capacity needed for survival in a changing environment, and its principles are shared across species. These principles have been studied since the inception of behavioral science, and more recently neuroscience has helped understand brain systems and mechanisms responsible for enabling aspects of memory. Here we outline the history of work on memory and its neural underpinni…

Hippocampal estradiol synthesis and its significance for hippocampal synaptic stability in male and female animals.
Increasing evidence points to an essential role played by neuron-derived neurosteroids, such as estrogen, on synaptic connectivity in the hippocampus. Inhibition of local estradiol synthesis results in synapse loss specifically in females, but not in males. Synapse loss in females, after inhibition of estradiol synthesis in hippocampal neurons, appears to result from impairment of long-term potent…

Rodent models of impaired fear extinction.
The measurement of Pavlovian forms of fear extinction offers a relatively simple behavioral preparation that is nonetheless tractable, from a translational perspective, as an approach to study mechanisms of exposure therapy and biological underpinnings of anxiety and trauma-related disorders such as post-traumatic stress disorder (PTSD). Deficient fear extinction is considered a robust clinical en…

Iron and mechanisms of emotional behavior.
Iron is required for appropriate behavioral organization. Iron deficiency results in poor brain myelination and impaired monoamine metabolism. Glutamate and γ-aminobutyric acid homeostasis is modified by changes in brain iron status. Such changes produce not only deficits in memory/learning capacity and motor skills, but also emotional and psychological problems. An accumulating body of evidence i…

Sex determines the neurofunctional predictors of visual word learning.
This study used functional MRI and an artificial language training paradigm to explore sex differences in the processing of a new writing system and how sex determines the optimal neural resource recruitment for visual word learning. Results indicated that males and females achieved equal learning outcome, and their learning curve followed a similar power function. They also showed similar overall…

Contributions of glucocorticoid receptors in cortical astrocytes to memory recall.
Dysfunctions in memory recall lead to pathological fear; a hallmark of trauma-related disorders, like posttraumatic stress disorder (PTSD). Both, heightened recall of an association between a cue and trauma, as well as impoverished recall that a previously trauma-related cue is no longer a threat, result in a debilitating fear toward the cue. Glucocorticoid-mediated action via the glucocorticoid r…

Neural correlates of the encoding of multimodal contextual features.
Functional magnetic resonance imaging (fMRI) was employed to identify neural regions engaged during the encoding of contextual features belonging to different modalities. Subjects studied objects that were presented to the left or right of fixation. Each object was paired with its name, spoken in either a male or a female voice. The test requirement was to discriminate studied from unstudied pictu…
