“…Recent experimental evidence has shown that some specific music (such as Mozart music) can decrease spontaneous apoptotic cell death, increase neurotrophic factors, neurogenesis, synaptogenesis, dendritic spine number, dendritic arborization, and change the levels of neurotransmitters or receptors in rodents (Kim et al 2006;Van Praag et al 2000;Chikahisa et al 2006). Exposure to music in the perinatal period enhances learning performance and alters BDNF/TrkB signaling in mice as adults (Castren et al 1992).…”

Patients with temporal lobe epilepsy (TLE) often display cognitive deficits. However, current epilepsy therapeutic interventions mainly aim at how to reduce the frequency and degree of epileptic seizures. Recovery of cognitive impairment is not attended enough, resulting in the lack of effective approaches in this respect. In the pilocarpine-induced temporal lobe epilepsy rat model, memory impairment has been classically reported. Here we evaluated spatial cognition changes at different epileptogenesis stages in rats of this model and explored the effects of long-term Mozart music exposure on the recovery of cognitive ability. Our results showed that pilocarpine rats suffered persisting cognitive impairment during epileptogenesis. Interestingly, we found that Mozart music exposure can significantly enhance cognitive ability in epileptic rats, and music intervention may be more effective for improving cognitive function during the early stages after Status epilepticus. These findings strongly suggest that Mozart music may help to promote the recovery of cognitive damage due to seizure activities, which provides a novel intervention strategy to diminish cognitive deficits in TLE patients.

There is increasing evidence that chronic noise stress impairs cognition and induces oxidative stress in the brain. Recently, orientin, a phenolic compound abundant in some fruits, millet, and herbs, has been shown to have antioxidant properties. This study investigated the potential effects of orientin against chronic noiseinduced cognitive decline and its underlying mechanisms. A moderate-intensity noise exposure model was used to investigate the effects of orientin on behavior and biochemical alterations in mice. After 3 weeks of the noise exposure, the mice were treated with orientin (20 mg/kg and 40 mg/kg, oral gavage) for 3 weeks. The chronic noise exposure impaired the learning and memory in mice in the Morris water maze and step-through tests. The noise exposure also decreased exploration and interest in a novel environment in the open field test. The administration of orientin significantly reversed noise-induced alterations in these behavior tests. Moreover, the orientin treatment significantly improved the noise-induced alteration of serum corticosterone and catecholamine levels and oxidative stress in the hippocampus and prefrontal cortex. Furthermore, the orientin treatment ameliorated the noise-induced decrease in brain-derived neurotrophic factor and synapseassociated proteins (synaptophysin and postsynaptic density protein 95) in the hippocampus and prefrontal cortex. Thus, orientin exerts protective effects on noise-induced cognitive decline in mice, specifically by improving central oxidative stress, neurotransmission, and increases synapse-associated proteins. Therefore, supplementation with orientin-enriched food or fruit could be beneficial as a preventive strategy for chronic noise-induced cognitive decline.

Objective: Noise has always been an important environmental public health issue for mankind. Although reports exist on hippocampaldependent spatial learning and memory (LM) impairment due to noise, there are only a few studies that have examined the effects of recovery from noise stress on LM impairments. Therefore, the present study investigated the effects of recovery from chronic noise exposure on LM deficits. Materials and Methods: In this study, the detrimental effects of noise stress on young male rats in the Morris water maze (MWM) were investigated at 1, 10, 20, 30, and 40 days after the discontinuation of chronic noise exposure of 80 dB or 100 dB for 4 h per day, for 30 days. The levels of monoamine neurotransmitters in the hippocampus were also evaluated by HPLC-EC at the end of each behavioral test. Results: Statistical analysis revealed that rats in the noise-treated groups failed to reach the same level of performance as the controls in the MWM. Further, the levels of dopamine (DA), norepinephrine (NE) and 5-hydroxytryptamine (5-HT) were significantly decreased in the hippocampus after noise exposure. However, the reduction in monoamine levels and impaired water maze performance recovered over time, so that by 30th day after cessation of noise exposure the 80 dB group showed no performance difference from the controls, and by 40th day, the 100 dB group also showed no performance difference from the control. Conclusion:Our findings suggest that noise impaired LM in young male rats and reduced monoamine neurotransmitters in the hippocampus. However, the noise-induced water maze deficits recovered over time, and the concurrent restoration of hippocampal monoamine neurotransmitter levels suggest that they are involved in LM impairments.
