Focal thalamic tracer
WebDec 17, 2016 · The projections between the thalamus and primary visual cortex (V1) are a key reciprocal neural circuit, relaying retinal signals to cortical layers 4 & 6 while being simultaneously regulated by massive layer 6 corticothalamic feedback. WebD-cis-(18)F-FPro appears to be a sensitive PET tracer for detection of secondary degeneration of TN after cortical injury. The uptake mechanisms of D-cis-(18)F-FPro remain to be elucidated, but the relationship to microglial activation suggests a diagnostic potential in various brain diseases.

WebDec 1, 2024 · The human thalamus has been suggested to be involved in executive function, based on animal studies and correlational evidence from functional neuroimaging in humans. Human lesion studies, examining behavioral deficits associated with focal brain injuries, can directly test the necessity of the human thalamus for executive function. WebThe focal or multifocal cortical stroke-like lesions typically have a T2 and FLAIR hyperintense signal, with restricted diffusion on DWI ( figure 5) in the acute phase, followed by increased signal on both DWI and ADC in the subacute and chronic phase. 10 These cortical signal changes are typically transient, most often leaving focal cortical …
