Devices, systems and methods to modify memory and/or cognitive function by delivering a sensory stimulus paired with learned material at opportune physiological periods during sleep. Described herein are systems, methods and devices to enhance a user's cognitive function in memorization and learning. A machine (e.g., a system or device) may be used to identify opportune periods of the sleep cycle and to deliver a stimulus during specific phases of the sleep cycle to facilitate or interrupt memory consolidation. The machine may record ambient sensory inputs during awake acquisition or reinforcement/relearning and replay all or an extracted form of the ambient sensory stimuli during a specified portion of the user's sleep. A stimulus may be delivered to a user to affect brain activity during sleep to modulate the phase of a user's sleep, quality of sleep, and/or quality or intensity of brain rhythms during a particular phase of sleep.

The invention relates to a graphics processing unit based matrix transpose optimization method. The method includes: converting an R-line S-column input matrix into a one-dimensional array, allocating storage spaces and copying data; setting a two-dimensional index space; computing global identifiers, workgroup identifiers and local identifies of work items; partitioning the matrix, and corresponding matrix partitions to workgroups; applying for local memories in the workgroups, copying the data into the local memories and synchronously waiting for completion of data copying; computing column and line indexes of the transposed data in a global memory; computing locations of output data in the global memory and local memories; assigning the data of the local memories to the one-dimensional array in the global memory to realize conflict-free memory consolidation access; and copying the one-dimensional array to the memories to form an S-line R-column superposed matrix.

The invention discloses a method and a terminal for assisting users in new word consolidation before and after reading. The method for assisting users in new word consolidation before and after reading includes that the terminal receives input signals for starting text reading or stopping text reading, acquires new word storage information from a new word storage database of a local memory, determines whether starting a new word consolidation function according to the new word storage information, starts the new word consolidation function and provides a new word learning interface when needing to start the new word consolidation function, wherein the new word storage information comprises new words to be consolidated; the terminal acquires corresponding new word learning data from a new word learning database and displays on a new word learning interface. A user can select to learn and consolidate the new words inquired when reading before and after reading so as to assist the user in deepening the memory and improve the word recognition and learning efficiency of the user.

Described is a system to accelerate memory consolidation using a steerable transcranial intervention. During operation, the system generates a unique transcranial and steerable stimulation tag to associate with memory of a task or event. Once the tag is generated, the system activates a plurality of electrodes (e.g., as few as four) to apply the unique transcranial stimulation tag during the occurrence of the event or task to be consolidated.

Described is a system for decoding and validating memory consolidation. During operation, the system receives electroencephalographic (EEG) data while a subject is performing a specific task. Nuisance signals are then removed from the EEG data, resulting in a nuisance free signal. Skill feature vectors are generated from the nuisance free signal using time-invariant feature extraction. A skill classifier can then be trained for the specific task based on the skill feature vectors to generate a subject specific model regarding a memory replay for the specific task. Finally, electrodes in a neural cap are activated based on the memory replay.
