recommendations! Published in 2024 at "Nature Biomedical Engineering"

DOI: 10.1038/s41551-024-01299-z

Abstract: Tactile feedback from brain-controlled bionic hands can be partially restored via intracortical microstimulation (ICMS) of the primary somatosensory cortex. In ICMS, the location of percepts depends on the electrode’s location and the percept intensity depends… read more here.

DOI: 10.1073/pnas.1916453117

Abstract: Significance Injecting small electrical currents into the somatosensory cortex evokes vivid tactile sensations that can be used to convey sensory feedback from brain-controlled bionic hands. To evoke intuitive touch percepts requires that we understand how… read more here.

DOI: 10.1088/1741-2552/ab4a24

Abstract: We have shown previously that microstimulation of the lumbar dorsal root ganglia (L5-L7 DRG) using penetrating microelectrodes selectively recruits distal branches of the sciatic and femoral nerves in an acute preparation. However, a variety of… read more here.

DOI: 10.1088/1741-2552/ab4c6c

Abstract: Somatosensory afferent pathways have been a target for neural prostheses that seek to restore sensory feedback from amputated limbs and to recruit muscles paralyzed by neurological injury. These pathways supply inputs into spinal reflex circuits… read more here.

DOI: 10.1101/2022.11.09.515803

Abstract: Cortical activity patterns occupy a small subset of possible network states. If this is due to intrinsic network properties, microstimulation of cortex should evoke activity patterns resembling those observed during natural sensory input. Here, we… read more here.

DOI: 10.1126/science.adq5978

Abstract: Intracortical microstimulation (ICMS) of somatosensory cortex evokes tactile sensations whose properties can be systematically manipulated by varying stimulation parameters. However, ICMS currently provides an imperfect sense of touch, limiting manual dexterity and tactile experience. Leveraging… read more here.

DOI: 10.1152/jn.00682.2019

Abstract: Humans and other animals are faced with decisions about actions on a daily basis. These typically include a period of deliberation that ends with the commitment to a choice, which then leads to the overt… read more here.

recommendations! Published in 2022 at "Frontiers in Behavioral Neuroscience"

DOI: 10.3389/fnbeh.2022.805178

Abstract: The goal of cortical neuroprosthetics is to imprint sensory information as precisely as possible directly into cortical networks. Sensory processing, however, is dependent on the behavioral context. Therefore, a specific behavioral context may alter stimulation… read more here.

DOI: 10.3389/fnhum.2017.00200

Abstract: Neuronal firing in the substantia nigra (SN) immediately following reward is thought to play a crucial role in human reinforcement learning. As in Ramayya et al. (2014a) we applied microstimulation in the SN of patients… read more here.

DOI: 10.3389/fnins.2022.812837

Abstract: Lost sensations, such as touch, could be restored by microstimulation (MiSt) along the sensory neural substrate. Such neuroprosthetic sensory information can be used as feedback from an invasive brain-machine interface (BMI) to control a robotic… read more here.

DOI: 10.3389/fpsyg.2022.836695

Abstract: Background Resistance training (RT) can offer beneficial physiological and psychological effects. The regular continuation of this exercise can be accomplished by improving the recovery and mood after a workout. Frequency-specific microcurrent (microstimulation) might offer a… read more here.
