abstract = {Stroke patients show some degree of spontaneous functional
recovery, but this is not sufficient to prevent long-term
disability. One promising approach is to characterize the
dynamics of stroke recovery genes in the lesion and distant
areas. We induced sensorimotor cortex lesions in adult
C57BL/6J mice using photothrombosis and performed qPCR on
selected brain areas at 14, 28, and 56 days post-stroke
(P14-56). Based on the grid walk and rotating beam test, the
mice were classified into two groups. The expression of cAMP
pathway genes Adora2a, Pde10a, and Drd2, was higher in poor-
compared to well-recovered mice in contralesional primary
motor cortex (cl-MOp) at $P14\&56$ and cl-thalamus (cl-TH),
but lower in cl-striatum (cl-Str) at P14 and cl-primary
somatosensory cortex (cl-SSp) at P28. Plasticity and axonal
sprouting genes, Lingo1 and BDNF, were decreased in cl-MOp
at P14 and cl-Str at P28 and increased in cl-SSp at P28 and
cl-Str at P14, respectively. In the cl-TH, Lingo1 was
increased, and BDNF decreased at P14. Atrx, also involved in
axonal sprouting, was only increased in poor-recovered mice
in cl-MOp at P28. The results underline the gene expression
dynamics and spatial variability and challenge existing
theories of restricted neural plasticity.Keywords: behavior;
