Basolateral amigdala
웹Pain is a multidimensional perception that includes unpleasant somatosensory and affective experiences; however, the underlying neural circuits that mediate different components of pain remain elusive. Although hyperactivity of basolateral amygdala glutamatergic (BLA Glu) neurons is required for the somatosensory and emotional processing of pain, the precise … 웹2024년 8월 3일 · The basolateral amygdala (BLA) is a temporal lobe structure that contributes to a host of behaviors. In particular, it is a central player in learning about aversive events …

웹2024년 7월 20일 · The amygdala is a limbic brain region that plays a key role in emotional processing, neuropsychiatric disorders, and the emotional-affective dimension of pain. Preclinical and clinical studies have identified amygdala hyperactivity as well as impairment of cortical control mechanisms in pain states. Hyperactivity of basolateral amygdala (BLA) … 웹2024년 4월 7일 · The basolateral amygdala (BLA) is the major input site for sensory information relating to both fear cues and threat information via the thalamus and sensory cortex. The BLA is connected to the central nucleus of the amygdala (CeA), which mediates expression of fear, and is reciprocally connected with key regions of the PFC (providing …
웹The basolateral amygdala, which is a region of the brain that is associated with the formation of fear memories, was stimulated in rats through the use of optogenetics in this article. The fact that the authors used optogenetics to investigate the causal effects that neural activity has on behavior is one of the most important strengths of the method, and it is also the most … 웹2009년 9월 23일 · Reductions in perceived stress correlated positively with decreases in right basolateral amygdala gray matter density. Whereas prior studies found gray matter modifications resulting from acquisition of abstract information, motor and language skills, this study demonstrates that neuroplastic changes are associated with improvements in a …
웹Animal models support the theory that abnormal activity of the anterior hippocampus, with aberrant modulation from the basolateral amygdala, could contribute to abnormalities downstream within a circuit that includes the striatum and cortex (Sah et al., 2003; Lodge and Grace, 2008, 2011). In an animal model, these circuit-based abnormalities ... 웹2024년 2월 8일 · In terms of addiction, the basolateral amygdala has shown involvement in people relapsing when it comes to drugs. Particularly, the amygdala integrates the influences of stress on drug-related memory (Wang et al., 2008). The amygdala has also shown to be influential when it comes to internet addiction.
웹2024년 9월 18일 · The basolateral amygdala (BLA) is critical for associating initially neutral cues with appetitive and aversive stimuli and receives dense neuromodulatory acetylcholine (ACh) projections. We measured BLA ACh signaling and activity of neurons expressing CaMKIIα (a marker for glutamatergic principal cells) in mice during cue-reward learning …
웹2024년 3월 3일 · We expressed GRAB DA in the basolateral amygdala (BLA), the nucleus accumbens (NAc), the medial prefrontal cortex (mPFC), or the lateral hypothalamic area (LHA) of mice and implanted optical fibers for photometry to examine the relationship between DA levels and each sleep-wakefulness state transition (Fig. 1 and fig. S1). We found three … burdije웹2013년 8월 5일 · Considering that the sub-nuclei of the amygdala have different functions, we further investigated the role of the basolateral amygdala (BLA) and the central amygdala (CeA) in pain chronicity separately.
