The constellation of behavior that resulted from amygdalae removal was called Kluver-Bucy syndrome, and it led to the amygdala being investigated for its role in fear. Since, the amygdala has become best known for its role in fear processing. When we are exposed to a fearful stimulus, ...
Effects of Amygdala Lesions Bilateral removal of the amygdala in monkeys produces striking behavioral changes which include tameness, a lack of emotional responsiveness, excessive examination of objects, often with the mouth, and eating of previously rejected items such as meat (Weiskrantz, 1956). The...
Taking into account recent concerns regarding rsfMRI research,22-24 we incorporated robust methods to address physiologic noise and participant motion during scanning, without global signal removal. We predicted that, similar to adults with MDD,15 adolescents with MDD would show diminished amygdala-...
Details of the es-fMRI procedure were also described elsewhere31,88. The subjects were scanned in resting condition (no task was delivered) on the day prior to electrode removal surgery. Blood-oxygenation-level-dependent (BOLD) images were obtained concurrently during intracranial electrical stimulation...
Functional volumes were preprocessed for motion correction, linear trend removal, spatial smoothing using a 5 mm FWHM Gaussian kernel, and elimination of low-frequency drifts using a temporal high-pass filter with a cutoff of 100 s. Preprocessing of the fMRI statistical maps included spatial ...
a reward is frustration or anger (if some action can be taken), or sadness (if no action can be taken). An example of an emotion produced by the omission or termination of a punisher (such as the removal of a painful stimulus, or sailing out of danger) would be relief. These example...
In hamsters, the total removal of the neocortex does not eliminate maternal behavior, but when this procedure is accompanied by lesions of the cingulate cortex and the underlying hippocampus, maternal behavior is abolished (Murphy et al., 1981). In primates, lesions to either the prefrontal cortex...
Immediately upon removal, the heart was washed in saline and the left anterior coronary artery was occluded at the same site as during MI surgery. Two ml of 0.5% Evans Blue was infused through the aorta to delimitate the area at risk (red) from the none-ischemic ...
models were set to be equally likely a priori before observing any data, and we applied Jeffreys-Zellner-Siow (JZS) prior (r scale = 0.354) to the regression coefficients. Results were only retained if there was at least moderate evidence (BF ≥ 3) after the removal of outliers....
Kim Peek: Kim Peek became famous due to the effects of his unusual brain, which had a split in the center rather than the usual corpus callosum connection. While he had difficulty with basic motor skills, he had a far great...
