Abstract:
Thesis advisor: John P. Christianson<br>In social species, animals must detect, evaluate and respond to the states of other individuals in their group. A constellation of gestures, vocalizations, and chemosignals enable animals to convey affect and arousal to others in nuanced, multisensory ways. Observers integrate such social information with environmental cues and internal physiology to general social behavioral responses via a process called social decision-making. The mechanisms and anatomical correlates of social decision-making, particularly those that allow behavioral responses to othe

Abstract:
Influential models highlight that insular cortex integrates cognitive, affective, sensorimotor and autonomic signals to create unified perceptual experiences or "feeling states". One challenge in developing a satisfactory neuropsychological model of insula function is to account for its involvement across these different domains which require access across multiple functional circuits. This thesis combines behavioural, psychophysiological, functional neuroimaging and lesion methods to inform and extend current models of integration in the insula.

Abstract:
The prefrontal cortex (PFC) is considered a critical node in the neural circuitry underlying drug-seeking behaviors. However, the mechanisms by which this region influences drug seeking and whether or not the lateral PFC mediates cocaine or heroin seeking are questions that have yet to be answered. To expand on the role of the PFC in drug seeking, rats were trained on either heroin or cocaine self-administration for a minimum of 12 days before undergoing extinction training and subsequent reinstatement tests (cued and drug-prime).

BACKGROUND AND OBJECTIVES: Obesity is emerging as the most significant health concern of the twenty-first century. A wealth of neuroimaging data suggest that weight gain might be related to aberrant brain function, particularly in prefrontal cortical regions modulating mesolimbic addictive responses to food. Nevertheless, food addiction is currently a model hotly debated. Here, we conduct a meta-analysis of neuroimaging data, examining the most common functional differences between normal-weight and obese participants in response to food stimuli.

A hiperexpressão do gene do fator de crescimento semelhante à insulina II (IGF-II) tem sido demonstrada na maioria dos carcinomas adrenocorticais em adultos. Os efeitos mitogênicos do IGF-II são mediados pela interação com o receptor de IGF-I (IGF-IR). Adicionalmente, o fator esteroidogênico 1 (SF-1) e o fator codificado por uma região crítica do cromossomo X associada ao sexo reverso e à hipoplasia adrenal congênita (DAX-1), ambos envolvidos no desenvolvimento e na esteroidogênese adrenal,

Abstract:
Our perception of the world is limited by the senses we are endowed with. In the case of taste, its functional fidelity is so critical for our survival that we come into the world with innate preference for sweet and disgust for bitter. These stereotyped behaviors are hardwired at the lowest levels of taste processing and they support the view that taste serves as an arbiter of the chemical world, passing judgement before permitting ingestion. Yet our experience of foods is manifold. This complexity results from distinct contributions from the sights, sounds and smells of the foods we consume.

A normative sample of 31 male subjects was selected from the community, ranging from the ages of 20 to 40 years old. Individual differences on empathy were assessed through the Questionnaire of Cognitive and affective Empathy (QCAE). Measures of grey matter volume, area, cortical thickness and white matter volume were extracted from T1-Wheighted structural MRI scans wit

Insular cortex is a brain region participated in processing of different sensory modalities. Evidences have also shown that posterior insular cortex may be related to somatosensory perception especially in nociception. However, the role for how PIC contributes to the initiation or maintenance of neuropathic pain is less understood. In the present study, permanent lesion by NMDA excitotoxicity in PIC was used to assess the

Abstract:
Long-term memories turn labile with reactivation and undergo a re-stabilization process, termed reconsolidation, involving molecular changes that allow updating of an existing memory trace. Such molecular changes may involve the activation of kinases and expression of proteins related to the increase of synaptic plasticity and memory formation. A kinase reported to have a role in a variety of memory tasks is the extracellular signal-regulated kinase 1/2 (ERK1/2). The downstream activation of ERK targets other regulatory enzymes, transcription factors and cytoskeletal proteins, which allow stru

Abstract:
Although the neural mechanisms regulating vomiting are well understood, the neurobiology of nausea is not. Unlike conditioned taste avoidance (CTA), conditioned disgust (indicated by orofacial gaping reactions) is a model of nausea-induced behaviour in rats because it is selectively produced by emetic drugs and anti-emetics attenuate it. Treatments that reduce serotonin (5-HT) availability selectively interfere with conditioned gaping (Limebeer and Parker, 2000; 2003) and forebrain serotonin is critical for the production of disgust reactions (Grill and Norgren, 1978b; Limebeer et al., 2004).

Abstract:
碩士<br>長庚大學<br>物理治療學系<br>102<br>Background: CPSP refers to the central pain from stroke. CPSP is attributed to a thalamic lesion, and may be associated with extrathalamic lesions. Recently evidences showed that insula cortex play an important role and involved the pain modulation of CPSP via its opioid receptors. However, it is unknown that the types of the opioid receptors on the insular cortex involve the re-looping of the central thermal disinhibition pathway to modulate the CPSP..
