Reward-related neural activity in ventral hippocampus
기억과 학습에 관여하는 것으로 알려진 해마는 공간적 정보를 처리한다고 알려져 있다. 해마는 해부학적으로 암몬각과 치아이랑으로 이루어져 있으며 특히 암몬각은 4개의 부위로 이루어져 있다. 이 중에 가장 많이 연구된 부분은 CA1이다. 해마는 크게 두 부분으로 나눌 수 있는데 배측해마와 복측해마로 나눌 수 있다. 이 두 부위는 다른 역할을 하는 것으로 알려져 있다. 최근 들어 해마와 보상의 연관성에 대한 연구가 많이 이루어지고 있으나 정확한 연관관계가 밝혀지지 않았다. 그래서 본 실험에서 복측해마에 초점을 맞추어 복측해마의 보상에 …

Individual Differences in Secondary Hyperalgesia and Associated Neural Activity
… research has identified group differences in neural activity associated with an individual’s propensity to develop a small or large area of secondary hyperalgesia (Asghar et al., 2015; Werner et al., 2013). In this study, I examined whether individual differences in the neural pain response …

TRPM5 Channels Contribute to Persistent Neural Activity and Working Memory
… including schizophrenia, attention deficit hyperactivity disorder, aging, and stress (Birnbaum et al., 2004; Goldman-Rakic, 1992; Goldman-Rakic and Selemon, 1997). Therefore, it is important to understand the neural basis of working memory. During performance of a working memory task, pyramidal …

Relaxing Music Effects on Implicit Racial Bias and Neural Activity
Music therapy has been used to treat a number of behavioral and emotional problems, including reducing the undesirable effects of having negative and traumatic associations with something/someone (e.g., PTSD). However, there have been no studies that have shown music therapy being used to treat …

Impact of Acute Ethanol Injections on Medial Prefrontal Cortex Neural Activity
… role of anesthesia on EtOH modulated mPFC activity, the present study investigated the effects of acute EtOH injections on mPFC neural activity in awake-behaving rodents. We utilized three groups: the first group received 2 saline injections during the recording. The second group received a …

From statistical mechanics to machine learning: effective models for neural activity
In the retina, the activity of ganglion cells, which feed information through the optic nerve to the rest of the brain, is all that our brain will ever know about the visual world. The interactions between many neurons are essential to processing visual information and a growing body of evidence …

Dynamic processes on complex networks : from disease spreading to neural activity
… behind the formation of cell assemblies in neural activity networks? From a neuroscience perspective: How can one explain functional compartmentalization in a globally-connected brain? Here we show that simple mechanisms of neural interaction allow for the emergence of robust cell assemblies …

Neural activity reveals effects of aging on inhibitory processes during word retrieval
<p>Word retrieval difficulties are one of the most frustrating problems in older adults. Poorer access to phonological (speech sound) representation of the target word has been postulated as the underlying deficit, supported by findings of improvement in word retrieval after phonological priming. …

Spatiotemporal Dynamics of Neural Activity During Human Episodic Memory Encoding and Retrieval
Throughout literary history, the ability to travel in time has been a source of wonder and amusement. Why this fascination with moving through time? One reason may be that people are especially attuned to the concept of time travel because we each possess our own personal mental time machine: …

Effect of hypoxia on spontaneous neural activity in the cortex of neonate mouse pups
… acute hypoxia occurring perinatally, on neuronal activity remain less studied. Spontaneous neural activity occurring during the first weeks of development is important for priming the nervous system to function efficiently when encountering sensory-evoked inputs. This calls for the need to …
