“…In addition, other types of memory likely involve interactions between different neural regions. In drug and reward learning, critical interactions occur between the VTA, infralimbic cortex and the nucleus accumbens (Day et al, 2013;Malvaez et al, 2013) and interactions between the amygdala and the insular cortex are critical for taste aversion memory formation and maintenance (Ferreira et al, 2005;Grossman et al, 2008;Bermudez-Rattoni, 2010). Moreover, the amygdala is an essential component of the fear memory circuit and amygdala lesions impair contextual memory even 28 days after training (Maren et al, 1996), suggesting that this region is also involved in memory maintenance However, it is not clear if the loss of memory is caused by the critical role of the amygdala in fear processing or in memory maintenance (Cui et al, 2004).…”

“…pairing of a neutral taste with an immunomodulating agent) [20][21][22]. It would also be convenient to clarify that many of the conditioned responses, in particular those that fall in the visceral associative learning are considered as non-declarative memories or implicit memories [23]. Appetitive and consummatory behaviours are significantly affected by the immune-derived molecules elicited by peripheral immune challenge resulting in innate and learned disease-avoidant ingestive behaviours.…”

Neuro-immune interactions are widely manifested in animal physiology. Since immunity competes for energy with other physiological functions, it is subject to a circadian trade-off between other energy-demanding processes, such as neural activity, locomotion and thermoregulation. When immunity is challenged, this trade-off is tilted to an adaptive energy protecting and reallocation strategy that is identified as 'sickness behaviour'. We review diverse disease-avoidant behaviours in the context of ingestion, indicating that several adaptive advantages have been acquired by animals (including humans) during phylogenetic evolution and by ontogenetic experiences: (i) preventing waste of energy by reducing appetite and consequently foraging/hunting (illness anorexia), (ii) avoiding unnecessary danger by promoting safe environments (preventing disease encounter by olfactory cues and illness potentiation neophobia), (iii) help fighting against pathogenic threats (hyperthermia/somnolence), and (iv) by associative learning evading specific foods or environments signalling danger (conditioned taste avoidance/aversion) and/or at the same time preparing the body to counteract by anticipatory immune responses (conditioning immunomodulation). The neurobiology behind disease-avoidant ingestive behaviours is reviewed with special emphasis on the body energy balance (intake versus expenditure) and an evolutionary psychology perspective.

“…Therefore, its effect to enhance consolidation and retrieval process might be related to its antioxidant activity. Recent findings showed that consolidation process involved protein synthesis (Bermudez-Rattoni, 2010). Previous study revealed that oxidative stress could disturb the function of protein contributing important role on consolidation process and resulting in memory impairment (Achat-Mendes et al, 2007).…”

Poor learning abilities and impaired memory are increasing their importance in accompany with the increased elderly population and stress exposure. Therefore, the development of cognitive enhancement is required. Recent findings showed that oxidative stress played the important role on the development of cognitive impairment in various conditions. Therefore the development of cognitive enhancer from vegetable possessing antioxidant is focused. The present study is carried out to determine the effect of dried tomato pomace powder on learning and memory both in normal and cognitive impairment conditions. Adult male Wistar rats, weighing 180-200 g, were orally given dried tomato pomace at various doses ranging from 2, 10 and 50 mg kg^-1 BW at a period of 14 days. The animals were determined the cognitive enhancing effect of tomato pomace after single dose, 7 and 14 days after administration. The results showed that tomato pomace significantly decreased escape latency but increased retention time. In addition, we also determined the cognitive enhancing effect of this substance in cognitive deficit condition. In this part, all animals were induced cognitive deficit using scopolamine injection via intraperitoneal route after 14 days of treatment. Again, tomato pomace also improved cognitive impairment. Tomato pomace is the potential cognitive enhancer. However, the precise underlying mechanism is still required further investigation
