The artificial synapse, measuring 150 by 200 micrometers, is composed of a cone-shaped microchannel filled with a solution of water and salt.
The conductivity of the channel adjusts accordingly based on impulse intensity or duration.
The length of the channel impacts how long it takes for concentration changes to dissipate.
Theoretical physicists from Utrecht University and experimental physicists from Sogang University have built an artificial synapse using water and salt.
This marks the first experimental proof that such a system can process complex information.
When it receives electrical impulses, ions within the liquid migrate through the channel, leading to alterations in ion concentration.
Theoretical physicists from Utrecht University in the Netherlands and experimental physicists from Sogang University in South Korea have made a groundbreaking discovery: they have built an artificial synapse that functions using water and salt, mimicking the behavior of synapses in the human brain. This marks the first experimental proof that such a system can process complex information.
The artificial synapse, measuring 150 by 200 micrometers, is composed of a cone-shaped microchannel filled with a solution of water and salt. When it receives electrical impulses, ions within the liquid migrate through the channel, leading to alterations in ion concentration. The conductivity of the channel adjusts accordingly based on impulse intensity or duration, mirroring strengthening or weakening of connections between neurons.
The length of the channel impacts how long it takes for concentration changes to dissipate. This suggests that channels can be tailored to retain and process information for varying durations, akin to synaptic mechanisms observed in our brains.
This research is significant as scientists continue their pursuit of enhancing the energy efficiency of conventional computers by emulating the human brain's extraordinary capacity. The findings appear in the journal Proceedings of the National Academy of Sciences.

This synapse is a minute device measuring 150 by 200 micrometers and mimics the behavior of a synapse, an essential component in the brain responsible for transmitting signals between neurons.
The artificial synapse comprises a cone-shaped microchannel filled with a solution of water and salt. Upon receiving electrical impulses, ions within the liquid migrate through the channel, leading to alterations in ion concentration.
Depending on the intensity (or duration) of the impulse, the conductivity of the channel adjusts accordingly, mirroring the strengthening or weakening of connections between neurons.
The length of the channel impacts the duration required for concentration changes to dissipate, suggesting the possibility of tailoring channels to retain and process information for varying durations akin to synaptic mechanisms observed in our brains.

The article contains an appeal to authority fallacy when the author states, 'This intriguing possibility lies at the heart of the burgeoning field of iontronic neuromorphic computing.' and 'It represents a crucial advancement toward computers not only capable of mimicking the communication patterns of the human brain but also utilizing the same medium.' The authors are considered experts in their field, but this does not automatically make their statements true or free from fallacies. Additionally, there is an example of inflammatory rhetoric when the author states, 'Remarkably, the initial findings materialized just three months later.' This statement creates a sense of excitement and importance without providing any actual evidence to support it.
