Description

Technical Field

[0001] This invention relates to the field of neural network circuit design, and in particular to an environment-emotional gradual associative memristor neural network circuit based on the TAP cell regulatory mechanism. Background Technology

[0002] In 1971, Chinese-American scientist Shao-Tang Tsai first proposed the concept of the memristor. While exploring the relationship between current, voltage, charge, and magnetic flux, he hypothesized that in addition to resistance, capacitance, and inductance, there should be a component that relates charge and magnetic flux—this is the memristor.

[0003] Memristors exhibit resistance plasticity, meaning their resistance can change significantly under the excitation of an external electric field; and the resistance changes in the opposite direction when the electric field direction changes. Memristors also possess threshold characteristics, meaning that in the resistive switching phenomenon of a memristor, there is a specific voltage or current threshold; when the applied voltage or current exceeds this threshold, the resistance state of the memristor changes.

[0004] Memristors possess key characteristics such as high operating speed, low power consumption, high integration density, and resistance flexibility. These characteristics enable memristors to demonstrate great potential in simulating biological synaptic plasticity in neuromorphic computing.

[0005] Memristor circuits have been proven to realize key biological synaptic mechanisms such as Hebb's learning rules, long-term duration enhancement (LTP), long-term duration inhibition (LTD), and pulse time-dependent plasticity (STDP). Memristor neural network circuits can also realize the function of biological associative memory, and neural network circuits related to associative memory have been proposed one after another.

[0006] In the brain, the hippocampus's core function is to recognize the current environment and generate an initial emotion corresponding to that environment; the amygdala receives external environmental stimuli, generates a new emotion based on the positive or negative state of the stimuli, and integrates this new emotion into the hippocampus to form long-term memory. Furthermore, the mapping between emotion and environment is not an instantaneous switch, but rather exhibits a gradual change.

[0007] There are transient amplification progenitor cells (TAPs) in the brains of adult mice that encapsulate and directly contact the mouse's neural stem cells (NSCs).

[0008] TAP cells have membrane-bound EfnB1 ligands on their surface. These ligands act directly on EphB2 receptors on NSCs, triggering Ca2+ receptors within NSC processes. 2+High-frequency oscillations prevent NSCs from entering the proliferation cycle, keeping them in a quiescent state.

[0009] When the number of TAP cells decreases (whether due to physiological needs or drug depletion), EfnB1-EphB2 signaling weakens and Ca²⁺ oscillations decay, prompting NSCs to activate and proliferate extensively to replenish the neural stem cell pool.

[0010] This invention, based on the resistance plasticity and threshold characteristics of memristors and combined with the TAP cell regulation mechanism of NSCs, proposes an environment-emotional gradual associative memristor neural network circuit. Structurally, this circuit mimics the hippocampus and amygdala of the brain, and its regulatory mechanism draws on the principle of TAP cells maintaining the resting or activated dynamics of neural stem cells (NSCs), enabling bidirectional gradual associative memory between environment and emotion. It can generate both positive and negative emotions, and a precise one-to-one mapping relationship can be established between environment and emotional state. This circuit can provide a reference for the hardware design of emotion computing and neuromorphic computing. Summary of the Invention

[0028] The regulatory mechanism of TAP cells refers to the following: when the number of TAP cells decreases (whether due to physiological needs or drug depletion), the EfnB1-EphB2 signal weakens and the Ca²⁺ oscillation decays, prompting NSCs to activate and proliferate extensively to replenish the neural stem cell pool. Therefore, the more the number of cells decreases, the more excited and active the NSCs become. Correspondingly, in the circuit, the weight of memristor synapses becomes larger.

[0043] like Figure 2 The diagram illustrates the regulatory mechanism of TAP cells. When the number of TAP cells increases, NSC cells maintain a low level of excitation and remain in a resting state; when the number of TAP cells decreases, NSC cells become excited and begin to differentiate into neurons.

[0044] like Figure 3 As shown, for the decrease in the number of TAP cells, when the value is greater than 0 (i.e., above the dashed line with a vertical axis value of 0), it indicates a decrease in TAP cells; when the value is less than 0 (i.e., below the dashed line with a vertical axis value of 0), it indicates an increase in TAP cells. Figure 3 It can be seen that the greater the decrease in the number of TAP cells, the faster the memristor synapse weight increases; at the same time, the greater the increase in the number of TAP cells, the faster the memristor synapse weight decreases.

[0045] like Figure 4The diagram illustrates the hippocampal-amygdala biological mechanism. When a mouse enters a new environment, the hippocampus recognizes and remembers the current environment and generates an initial mood based on it; while the amygdala is responsible for receiving external stimuli and generating a current mood for the current environment. The hippocampus then integrates this current mood with the initial mood of the environment to form an overall mood.

[0046] like Figure 5 As shown, V es V represents the emotional stimulus signal applied to the amygdala module by external forces in the current environment. ce V represents the current mood voltage generated in the amygdala module. o_emo V represents the voltage after integration by the emotion-generating neuron module in the hippocampus. o_env This represents the recognition voltage of the environment recognition neuron module in the hippocampus in response to the current environment. Also known as the environmental characteristic voltage, this voltage is the unique identifier used by the neuron to mark the current environment and is independent of the mood-related stimulus signal V. es The situation changes. T1 and T2 are a pair of inverted clock signals, and the circuit training process can be divided into four steps. In step (a), no mood stimulus signal V is applied to the circuit. es At this time, the corresponding current mood voltage V ce The voltage is 0V. Simultaneously, the circuit learns from the current environment and generates a mood voltage V corresponding to that environment. o_emo and environmental characteristic voltage V o_env Because no mood-stimulating signal, i.e., V, was added. es Since V is 0V, therefore V o_emo It will move closer to the initial mood voltage corresponding to the current environment. In step (b), a positive mood stimulus signal, V, is applied to the circuit. es The voltage is positive; at this time, the current mood voltage V in the amygdala module is... ce Increase, and at the same time, because the hippocampus will increase the current mood voltage V ce Integrating with the initial mood voltage, the subsequent overall mood voltage V o_emo It is in an upward state due to the environmental characteristic voltage V o_env It is a unique identifier for the current environment, so V will be used in subsequent adjustments. o_env All will remain unchanged. In step (c), a negative mood stimulus signal, V, is applied to the circuit. es The voltage is negative; at this time, the current mood voltage V ce It shows a downward trend, while the overall mood voltage V o_emo It also shows a downward trend. In step (d), the external environment's excitation signal to the circuit becomes 0V, i.e., V. esWhen the voltage is 0V, the circuit will retain the previously learned results and will not change. Therefore, the circuit can form a long-term memory of the current environment.
