Cerebral Blood Flow Imaging Dataset of SD Rat under Resting-State and Task-Evoked Conditions

The sample cohort consists of a unique set of 23 adult rats, divided into two independent acquisition subsets.The dataset is strictly organized according to standardized data structures and specifically includes the following two core components:Baseline Resting-State Data (N=14): This subset encompasses resting-state CBF images of the somatosensory motor cortex from 14 rats, with a sampling duration of 10 minutes and a sampling rate of 10 Hz.Resting-State vs. Evoked-State Comparative Data (N=9): This subset covers CBF images of the left hemisphere from 9 rats.

The resting-state data were acquired for 5 minutes at a sampling rate of 4 Hz. For the whisker stimulation-evoked data, the sampling rate was 10 Hz, with each single acquisition lasting 85 seconds and repeated at least 30 times per rat.
