2011 Molecular Psychiatry  
Here, we report that an AKT1 variant (rs1130233) previously associated with AKT1 protein expression, prefrontal function and schizophrenia, affects human MTL structure and memory function.  ...  AKT1 controls important processes in medial temporal lobe (MTL) development and plasticity, but the impact of human genetic variation in AKT1 on these processes is not known in healthy or disease states  ...  and associated prefrontal structure and function. 11, 12 Aberrant development and plasticity of the medial temporal lobe (MTL) is also critically implicated in schizophrenia and may involve genes controlling  ...

Thalamo-Cortical Disruption Contributes to Short-Term Memory Deficits in Patients with Medial Temporal Lobe Damage

Natalie L. Voets, Ricarda A. L. Menke, Saad Jbabdi, Masud Husain, Richard Stacey, Katherine Carpenter, Jane E. Adcock
2015 Cerebral Cortex  
Short-term (STM) and long-term memory (LTM) have largely been considered as separate brain systems reflecting frontoparietal and medial temporal lobe (MTL) functions, respectively.  ...  Whereas thalamo-temporal functional connectivity reflected LTM performance, thalamo-prefrontal functional connectivity specifically predicted STM performance.  ...  Such evidence for thalamic atrophy raises the possibility that, in the context of MTL injury, altered integrity of thalamic nuclei, and disruption of their associated respective thalamo-cortical functional  ...
