Whole-brain traumatic controlled cortical impact to the left frontal lobe: Magnetic resonance image-based texture analysis.

This research assesses the capability of texture analysis (TA) derived from high-resolution (HR) T2-weighted magnetic resonance imaging to identify primary sequelae following 1-5 hours of controlled cortical impact mild or severe traumatic brain injury (TBI) to the left frontal cortex (focal impact) and secondary (diffuse) sequelae in the right frontal cortex, bilateral corpus callosum, and hippocampus in rats. The TA technique comprised first-order (histogram-based) and second-order statistics (including gray-level co-occurrence matrix, gray-level run length matrix, and neighborhood gray-level difference matrix). Edema in the left frontal impact region developed within 1 hour and continued throughout the 5-hour assessments.

Converging diencephalic and hippocampal supports for episodic memory.

To understand the neural basis of episodic memory it is necessary to appreciate the significance of the fornix. This pathway creates a direct link between those temporal lobe and medial diencephalic sites responsible for anterograde amnesia. A collaboration with Andrew Mayes made it possible to recruit and scan 38 patients with colloid cysts in the third ventricle, a condition associated with variable fornix damage.

The Transporters Abc1 and Abc6 Are Important for Xenobiotic Resistance, Trichothecene Accumulation, and Virulence to Wheat.

The plant pathogenic fungus is the causal agent of Fusarium head blight (FHB) disease on small-grain cereals. produces trichothecene mycotoxins such as deoxynivalenol (DON) that are required for full virulence. DON must be exported outside the cell to cause FHB disease, a process that may require the involvement of membrane-bound transporters.

Neural, psychological, and social foundations of collective memory: Implications for common mnemonic processes, agency, and identity.

Recent advances in memory research within psychology and neuroscience have contributed to a shift from examining memory through an individualistic lens towards a growing recognition of potential social and collective influences on mnemonic processes. This shift is prominently illustrated by continuing research on collective memory. Through a scoping literature review, we identify three crucial components defining collective memory: memories held in common across individuals within a social group, which are centrally important to group identity, and which impact significantly on perceived group agency.
