    MEMO platform

    MEMO platform consists of modular parts including microfluidic device, microelectrode array, gas supply chamber and neuronal cells. Uniquely, MEMO enables seizure-like activity detection and drug response analyses in functional level. Moreover, MEMO is suitable for  biochemical analyses e.g., RNA collection.

    • The three-compartment microfluidic device enables the formation of functional circuitry of neuronal networks for mimicking brain functions

    • Customized microelectrode array (MEA) enables the electrical measurement of neuronal activity for detecting epileptic seizures

    • Medium reservoirs enable to store the mediums for maintaining the cell cultures

    • Gas supply chamber (+ plastic lid and silicon-based PDMS gasket) enables the microenvironment control for a long period

    • Human pluripotent stem cell (hPSC)-derived neurons enable to model better human responses

    • Seizures can be induced with chemical stimulation e.g., kainic acid (KA) or appear endogenously in patient-derived cells

    Microfluidic device 

    MEMO platform consists of microfluidic device, in which three separate compartments are connected with each other by microtunnels. The microfluidic device enables the formation of neuronal network circuitry on a chip, mimicking brain functions.

    Microfluidic device consists of three cell culture compartments to culture three different neuronal network populations separately. Compartments are connected with microtunnels that allows neuronal soma isolation in distinct compartment and  axonal growth from one compartment to another compartment. This enables the formation of neuronal network circuitry on a chip.

    Separate medium reservoir part enables to store medium for maintaining the cell cultures. In addition, compartmentalization enables to manipulate one neuronal population at time. 

    Seizure-like activity can be induced with chemical stimulation, e.g., kainic acid, or it appears endogenously with patient-derived cells. 

    Use of human pluripotent stem cells (hPSC)-derived neurons enables to model better human responses. Moreover, MEMO platform is compatible with e.g., rodent neuronal cells.

    Microelectrode array

    MEMO platform consists of custom made microelectrode array (MEA), on which the microfluidic device is attached. MEA enables the follow-up recordings of neuronal cultures, detection of seizure-like activity and drug response analysis. 

    MEA contains up to 120 electrodes that are placed under every neuronal network compartment.

    ​

    MEA enables the follow-up recordings, seizure-like activity detections and drug response analyses in neuronal network and neuronal circuitry levels.

    ​

    Separate gas supply chamber enables to control the microenvironment, allowing longer measurements and follow-up recordings. 

    ​

    MEMO platform is compatible with Multi Channel System MEA headstage.

    Data Analysis

    Microelectrode array recordings create large amount of electrophysiological data, which are analyzed by own smart algorithms. 

    MEA measurements give valuable information of

    • Neuronal network maturation

    • Seizure-like activity, spreading and suppression

    • Drug responses

    Our smart algorithms can analyze >25 parameters, e.g.,

    • Single spikes, spike trends

    • Burst, synchronous burst 

    • Circuitry burst 

    • Etc.
