1. Origem da inervação dopaminérgica da divisão central da amígdala expandida e da concha do núcleo Acumbens no rato. / Origin of dopaminergic fibers to the central extended amygdala and nucleus accumbens shell in the rat.
A amígdala expandida central (EAc) inclui os núcleos central da amígdala (CeA), intersticial lateral da estria terminal (BSTl), intersticial do ramo posterior da comissura anterior (IPAC) e amígdala expandida sublenticular (SLEA). A EAc e a concha do acumbens possuem densa inervação dopaminérgica, implicada em processos motivacionais, e cuja origem fo

2. Afferent connections of the amygdalopiriform transition area (APir) of the rat. / Conexões aferentes da área de transição amígdalo-piriforme (APir) no rato.
The amygdalo-piriform transition area (APir) lies at the junction of the piriform, periamygdaloid and entorhinal cortices. The afferent connections of this olfactory district were studied with retrograde tracing methods using the cholera toxin B subunit and Fluoro-Gold as tracers. Our retrograde experiments showed that the main input sources to APir derive f

3. Impaired Emotional Declarative Memory Following Unilateral Amygdala Damage
Case studies of patients with bilateral amygdala damage and functional imaging studies of normal individuals have demonstrated that the amygdala plays a critical role in encoding emotionally arousing stimuli into long-term declarative memory. However, several issues remain poorly understood: the separate roles of left and right amygdala, the time course over

4. Contextual and Auditory Fear Conditioning are Mediated by the Lateral, Basal, and Central Amygdaloid Nuclei in Rats
A large body of literature implicates the amygdala in Pavlovian fear conditioning. In this study, we examined the contribution of individual amygdaloid nuclei to contextual and auditory fear conditioning in rats. Prior to fear conditioning, rats received a large electrolytic lesion of the amygdala in one hemisphere, and a nucleus-specific neurotoxic lesion i

5. Newly generated neurons in the amygdala and adjoining cortex of adult primates
The subventricular zone remains mitotically active throughout life in rodents. Studies with tritiated thymidine, which is incorporated into the DNA of mitotic cells, have revealed that the rodent subventricular zone produces neuroblasts that migrate toward the olfactory bulb along the rostral migratory stream. A similar migratory stream has been documented i

6. The relationship of the locus coeruleus to the amygdala in the cat.
In eight cats a unilateral lesion was produced in the locus coeruleus using either a 20 degree or a 30 degree rostrocaudal parasagittal electrode approach. The animals were killed after a survival period of 10 days. Ascending locus coeruleus projections found in the five animals with the best area destruction went through the dorsal pontine tegmentum into th

7. Gene expression evidence for remodeling of lateral hypothalamic circuitry in cocaine addiction
By using high-density oligonucleotide arrays, we profiled gene expression in reward-related brain regions of rats that developed escalated cocaine intake after extended access to cocaine (6 h per day). Rats allowed restricted daily access to cocaine (only 1 h) that displayed a stable level of cocaine intake and cocaine naive rats were used for controls. Four
