Outcome Measures

Primary Outcomes (2)

  • Acquire neuronal structual (image frame) results of different brain regions

    By interpreting the microscopic images of different brain regions' tissues , an attempt is made to understand the structure of brain disease tissues (via cell morphology, microvessels, etc).

    3 years

  • Acquire electrophysiological readout (voltage amplitude, mV) datas of different brain regions

    By interpreting the neuron electric reactive datas, an attempt is made to know the neuronal activity (via detecting voltage amplitude change) between multiple neurons.

    3 years

Secondary Outcomes (1)

  • To conduct imaging for multiple types of human brain tissues and construct the neuron image database

    3 years

Study Arms (2)

Multiphoton microscopy

EXPERIMENTAL
Device: Multiphoton microscope

Electrophysiological system

EXPERIMENTAL
Device: Electrophysiological system

Interventions

Electrophysiological system is used for examining voltage variation in biological samples. And multiphoton microscopy is a common type of nonlinear optical microscope.

Electrophysiological system

Multiphoton microscope acquires high-resolution image based on nonlinear optics and can be used for detect biological specimens.

Multiphoton microscopy

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • \. Patients older than the age of 18 with diagnosis of brain disease (both newly-diagnosed or recurrent) who are suitable and willing to receive resection surgery.

You may not qualify if:

  • Patients who cannot give consent to participate in the study.
  • The tumor samples failed to give a conclusive pathological diagnosis by standard pathological workflow.
  • Patients who only receives biopsy surgery rather than resection surgery.
  • Significant post-irradiation effect or radiation necrosis reported in the pathological examination.
