Individual Sequence Representations in the Medial Temporal Lobe
Much of what we need to remember consists of sequences of stimuli, experiences, or events. Repeated presentation of a specific sequence establishes a more stable long-term memory, as shown by increased recall accuracy over successive trials of an STM task. Here we used fMRI to study the neural mechanisms that underlie sequence learning in the auditory-verbal domain. Specifically, we track the e...
متن کاملSequence of Abeta-protein deposition in the human medial temporal lobe.
The deposition of Abeta protein (Abeta) and the development of neurofibrillary changes are important histopathological hallmarks of Alzheimer disease (AD). In this study, the medial temporal lobe serves as a model for the changes in the anatomical distribution pattern of different types of Abeta-deposits occurring in the course of AD, as well as for the relationship between the development of A...
متن کاملTemporal effects in sequence learning
Through the use of double task conditions, the sequence learning (SL) paradigm offers unique opportunities to study the relationships between learning and attention. In their original study, Nissen & Bullemer (1987) argued that a secondary tone-counting task prevents SL because it exhausts participants’ attentional resources. Other authors have instead suggested that the detrimental effects of ...
متن کاملBiologically Inspired Temporal Sequence Learning
We propose a temporal sequence learning model in spiking neural networks consisting of Izhikevich spiking neurons. In our reward-based learning model, we train a network to associate two stimuli with temporal delay and a target response. Learning rule is dependent on reward signals that modulate the weight changes derived from spike-timing dependent plasticity (STDP) function. The dynamic prope...
متن کاملAn fMRI Study of the Role of the Medial Temporal Lobe in Implicit and Explicit Sequence Learning
fMRI was used to investigate the neural substrates supporting implicit and explicit sequence learning, focusing especially upon the role of the medial temporal lobe. Participants performed a serial reaction time task (SRTT). For implicit learning, they were naive about a repeating pattern, whereas for explicit learning, participants memorized another repeating sequence. fMRI analyses comparing ...
