From the perspective of comparative morphology, the distribution of non-monoaminergic neurons in the common marmoset (Callithrix jacchus) was investigated using an immunohistochemical method with specific antibodies to tyrosine hydroxylase (TH) and aromatic-L-amino acid decarboxylase (AADC).TH-immunoreactive (IR) neurons (but not AADC-IR) neurons were observed in the olfactory tubercle, preopti...

In this fMRI study, we investigated prefrontal cortex (PFC) and visual association regions during selective information processing. We recorded behavioral responses and neural activity during a delayed recognition task with a cue presented during the delay period. A specific cue ("Face" or "Scene") was used to indicate which one of the two initially viewed pictures of a face and a scene would b...

We applied a sensitive new functional magnetic resonance imaging technique to identify the pattern and determinants of cocaine-induced brain activation in drug-naive rats. At doses greater than 0.1 mg/kg iv, cocaine produced robust activation throughout cortex with the largest magnitude increase in frontal neocortex. Additionally, we detected selective activation within dopamine-innervated subc...

The capacity to accurately evaluate the causal effectiveness of our actions is key to successfully adapting to changing environments. Here we scanned subjects using functional magnetic resonance imaging while they pressed a button to earn money as the response-reward relationship changed over time. Subjects' judgments about the causal efficacy of their actions reflected the objective contingenc...

Background Peer adversity and aggression are common experiences in childhood adolescence which lead to poor mental health outcomes. To date, there has been no review conducted on the neurobiological changes associated with relational peer-victimisation, bullying cyberbullying. Methods This systematic assessed structural functional brain bullying, cyberbullying from 1 January 2000 April 2021. A ...
