Legged robots operating in real-world environments must possess the ability to rapidly adapt to unexpected conditions, such as changing terrains and varying payloads. This paper introduces the Synaptic Motor Adaptation (SMA) algorithm, a novel ...

• We proposed the framework of transcranial focused ultrasound (tFUS) stimulation integrating our two previously proposed methods for tFUS transducer ...

As a novel non-invasive human brain stimulation method, transcranial focused ultrasound (tFUS) is receiving growing attention due to its superior spatial specificity and depth penetrability. Since ...

Neural networks have been widely used in agent learning architectures; however, learnings for one task might nullify learnings for another. Behavioural plasticity enables humans and animals alike to respond to environmental changes without degrading ...

Rapid online adaptation to changing tasks is an important problem in machine learning and, recently, a focus of meta-reinforcement learning. However, reinforcement learning (RL) algorithms struggle in POMDP environments because the state of the system, ...

Volume transmission is an important neural communication pathway in which neurons in one brain region influence the neurotransmitter concentration in the extracellular space of a distant brain region. In this paper, we apply asymptotic analysis to a ...

Neuromodulation is a promising treating therapy for drug-resistant epilepsy. Studies have shown that electrical stimulation could induce post-stimulus inhibition of neural activity, making it available for aborting seizure. Considering the long-term ...

Recently, there has been growing interest in analyzing the relationship between sleep quality and brain capacities, in terms of memory consolidation and the possible appearance of degenerative diseases such as dementias, including Alzheimer. This paper ...

In nature, gene regulatory networks are a key mediator between the information stored in the DNA of living organisms their genotype and the structural and behavioral expression this finds in their bodies, surviving in the world their phenotype. They ...

This paper presents a discrete model of non-synaptic interactions between neurons, which are performed by special chemical agents, neurotransmitters. In this model, all signals are broadcast: each neuron's activity can be perceived by all other neurons ...

Transcranial magnetic stimulation and transcranial direct current stimulation are two techniques of non-invasive brain stimulation which principal mechanism of action is the cortical excitability modulation. The objective of this study is to perform an ...

In this work I explore bio-inspired architectures for adaptive and smart sensing incorporating two key aspects present on the insect brain that are not found in more traditional neural network approaches: modulated, hierarchical processing and modulated ...

Volume transmission is a fundamental neural communication mechanism in which neurons in one brain nucleus modulate the neurotransmitter concentration in the extracellular space of a second nucleus. In this paper, we formulate and analyze a mathematical ...

Many animals predict the outcomes of their actions by internal models. Such "forward models'' enable animals to rapidly simulate many actions without performing them to choose an appropriate action. Robots would similarly benefit from forward models. ...

In this paper, we use a gene regulatory network (GRN) to regulate a reinforcement learning controller, the State- Action-Reward-State-Action (SARSA) algorithm. The GRN serves as a neuromodulator of SARSA's learning parame- ters: learning rate, discount ...

Transcranial focused ultrasound FUS has emerged as a noninvasive neuromodulatory modality with exquisite depth penetration and spatial selectivity. Liquids, such as degassed water or mineral oil, are used as acoustic coupling media between the ...

Abstract Algorithms for evolving agents that learn during their lifetime have typically been evaluated on only a handful of environments. Designing such environments is labour intensive, potentially biased, and provides only a small sample size that may ...

Ubiquitous access to computers, cell phones, internet, personal digital devices, cameras and TV can be attributed to advances in the very large scale integration (VLSI) technology and the advances in circuit design to operate circuits at Gigahertz ...

The spatial specificity and controllability of focused ultrasound (FUS), in addition to its ability to modify the excitability of neural tissue, allows for the selective and reversible neuromodulation of the brain function, with great potential in ...

The wireless implantable/intracavity micromanometer (WIMM) system was designed to fulfill the unmet need for a chronic bladder pressure sensing device in urological fields such as urodynamics for diagnosis and neuromodulation for bladder control. ...

Regional modulation of the level of cortical neurotransmitters in the brain would serve as a new functional brain mapping technique to interrogate the neurochemical actions of the brain. We investigated the utility of the application of low-intensity, ...
